I did few things to my T a few days ago. I swapped out oil, oil cooler seal, pvc valves and I also did the coolant throttle body bypass mod and installed a k&n drop in filter. Still pulls hard just not as hard as before all this. But I also did an ecu reset so I'm not sure if that can be involved. I didn't expect the k&n to do anything for me I just bought it save money on the paper filters. Second since I bought the truck and already at 40$. So I bought the k&n thats washable. But back to topic what do you think is making me loose the tiny bit of top end?

An oiled filter? Probably fouled your MAF sensor.

 

[berto07T]

Think so? It was brand new and felt the inside of the little plastic bag in came in and it was dry. The only thing that had a tiny bit of oil residue was the rubber border where it seals when you close the air box. I'll try cleaning my maf sensor today. I was figuring maybe it was cause I did the ecu reset. So it just relearning.

 

[4mula1fan]

Be careful cleaning it and only use cleaner for MAF sensors.

 

[nightowl]

Yeah a overly oiled filter will do that. I went with a dry filter to prevent it since I'm not in a lot of dirt and dust with my Titan.

Okay so update. I cleaned the MAF sensor and no change. So I decided to record some 0-60 runs with the torque pro app and an obdII adapter so I get reading straight from the ecu. I did two runs each and I'm tripped out on the outcome. Don't mind the other boxes still trying to figure out the app but take a look at the 0-60 times and the rpms and hp and torque to the wheels..
First run with k&n drop in filter

Second run with k&n drop in filter

First run with regular paper filter

Second run with regular paper filter


As you can see with the k&n I lost 2hp to the wheels after the first run but lost about 30 ft lbs of torque! Wtf? The only thing the k&n did was let me get my rpms higher because with the regular paper filter highest it went both runs was 3675 so it does flow more air but I lose torque. Why? My truck is all stock except for airbox mod and now TB bypass mod. I was thinking of picking up a bully dog power pup tuner they have it for sale for real cheap just to try it for performance wise and economy wise since they have different tunes. Also I pump 91. Previous owner pumped 91 since new so I didn't want to change that.. so what is your guys takes/opinions? The k&n drop in filters suck? Unless I'm chipped (have a tuner) or maybe give the computer more time to relearn after the ecu reset? It's been 350 miles now since install.. so I doubt it's that

Time for UpRev

Time for UpRev

Lol! Wish I could afford that! I'm in the blisteins and tuner world can't afford the coil overs and uprev world lol:big_grin:

What do you guys think about the bullydog power pup? Saw a good deal on one. But I have never used one before.

Do yourself a favor. For the price you pay for a little tuner, you might as well save just a little more and get uprev. There is not a single regret from those of us that sold our tuners and swtiched. It is a world of difference and doesn't cost a whole lot more.

The one i found is a pretty good deal. Half the price of a new one so as long I don't get a married one which is why I'm asking what to look for..Doesn't it start at 700$ ? And then it's a little extra for package deals no? What's the difference between handheld like bully dog and uprev? Dont They all do the same WOT removal advance timing speed limiter etc basically except you have down time with uprev and it's "custom tuning" with the air and fuel ratios? And I hope it's not just like fanboy thing it is with uprev like it was with the radflos.. if you read all the old threads everyone was saying radflos. Years later everyone is saying they suck they clunk they make other noises.. Another thread that's old I'll look it up later and post a link where people where waiting for the bully dog power pup release a few years back. People with uprev were getting only like 11hp extra as opposed to the 23 hp with the premium tune on.. I think custom tuning to me is worth it when you start doing engine work not just bolt ons.. like cams spring & retainers pistons etc. But of course that's only my opinion..but why do you think the k&n made me lose power and speed? It's still shocking me wasn't expecting anything from it except to save me on paper filters but it took power ! Lol

Ok. So Uprev is like $500. You get 3 tunes right off the bat. (91 octane tune, valet tune, or a "won't start" tune so it can't be stolen) When you get the cable in the mail, you plug it in the truck and then to a laptop. You do some normal cruising and a couple 0 to 60 runs WOT. You then send the trucks ECU info to a tuner (Joe or Seymour on here). He will make necessary adjustments based on your truck info. Not just preset values like a hand held tuner. You would do this probably 3 times over a few days reflashing the ECU with a new tune as they get emailed back to you until it's running perfect. Uprev is a proven performance upgrade that blows the handheld tuners away. Again, no preset values. Uprev does WAY more than anything else. It just doesn't have a fancy little screen like the handhelds.

I'm not sure about your power loss. I don't see what type of exhaust you have. If you have a pre 2008 truck, the stock y pipe robs power as well as the stock muffler. The engine is drawing in plenty of air but is it able to expel it effectively? Maybe air cant get out as effciently as its drawn in. Just a thought.

And custom tunes are great for any truck, especially those with just bolt ons. Very few on this site have deep engine work done. Uprev has done everybody with simple bolt ons wonders. Makes a huge difference. I sold my Bullydog gt a couple months ago and never looked back. I paid almost 400 for it and sold it for like 225 ish. I could have just bought uprev and skipped the hassle.

Thank you, appreciate you clarifying that for me! Now that cable you say goes form the obd plug to usb for computer? So I don't need to purchase that cipher thing I read about? So I guess it isn't tuning like before or other companies where you have to send in your ecu. So the 91 is like the premium/performance tune? And valet? Can you explain what that one does? And so I can switch from one to another at home just have to flash it with my computer? And say I get another bolt on do I have to pay to get it retuned? Or do I just send another data log? Thanks again for clarifying that and the price. I thought it was more expensive but 500$ isn't that bad, as much as some newer hand helds.

I have an 07.. this is funny now that you asked I went and looked (don't know why I never looked when I bought it and did the rear differential fluid) It has a Flowmaster and with the codes on it it looks like it's the 70 series. Previous owner never said anything. So can I purchase a better flowing y pipe and just clamp it or do those have to be welded on? What about gutting my secondary cats? What's your take on that?

 

[robstrevor]

So with Uprev, all your tuning is done via email. So you plug the cable into the truck and other USB end into the comouter. The Uprev software includes Osiris and Cipher. It's part of the package and you download it for free. The tunes I know of would be like 87 octane tune, 91 tune, or valet, which you can select at anytime with the truck off. So valet mode, you can limit the rpms and vehicle top speed so people don't go romping around in your truck. Then there is security mode which when selected, the truck won't start. You select with the cruise control buttons. If you decide to do bolt ons later and require a new tune, I've heard Joe (Seymour) has send over tunes at no cost later on. I don't want to speak for him and say that's for sure however. So when you flash the ECU it's done with your laptop and takes all of 20 to 30 secs to actually reflash. It's very fast. I STRONGLY recommend contacting Seymour and talking to him about it. He has is the man when it comes to Uprev and Titans. He will give you more details on Uprev and tell you what's best for your application regardless if you purchase from him or not. Best customer service in the business. And yes swapping out the Y pipe with a flowmaster one will free up some exhaust flow. Welding is recommended. I'd contact Nightowl on here or visit Cajunbpipes.com. the Cajun guys include Nightowl and Seymour. They will tell you the same thing I am. I'm not trying to blow smoke up your a$$. I'm just a guy who has been there and done that. If you plan on keeping the truck, uprev will serve you very well.

Gutting the cats isn't necessary recommended as it creates more turbulent exhaust flow in that expanded area of the pipe which will decrease the scavenging (siphoning of exhaust gasses out of the cylinders from expanding gasses in the exhaust system) effect of the exhaust, therefor robbing power. Conveniently enough, Cajun makes and sells catless b pipes for a good price. This way you will have those cats deleted to free up some power and sound. They have an extended bung for the O2 sensor as well so you won't throw any codes either. You should seriously contact them about the b pipes, uprev, and y pipe. I guarantee you, you will be happy you did. It is an investment but if you plan on hanging to the truck for a while it's the best option. do it right the first time and you won't have to do it again.

To clarify I believe the only years that get three maps are 04 maybe 05. After that you have 5 maps to be of your choice.

 

[robstrevor]

Ah. I had it wrong then. I thought the early years only got 1 map and the others got 3
