Here is a little project I am working on to better consolidate/track all the differences performance mods make. I will keep a master excel spreadsheet of all of this. If anyone would like to update some of the info or add to it, either post it in this thread or pm it to me.
Consolidation of mods, dynos, and track times

CaptFDU, do you have a bigger pic of you A/F ratio with dyno chart. It seems you are running pig rich and I'll bet you are loosing a lot of power due to it. Ideally you want to have ~12.8-13.0 A/F ratio to maximize hp. I have never seen one run as rich as yours. Do you have any exhaust mods?

Wow...you got some good eyes, Z. I can barely make it out, but it looks to me like his afr was at about 10:1, or even lower. During my runs, I was at an almost perfect 13:1 throughout.

I will try to attach a larger pic. The guy that was doing the dyno said same thing about running very rich. I'm not sure how that can be fixed just yet, but he was going to do some research for me. This was a baseline dyno run 3 days after i bought the truck. No mods at all so we could see how much improvement we are actually getting. Any ideas on how the lean the truck out???GETSOMZ28 said:
Me too. My AFR was dead on. A little richer around max toque and leaned up at max hp. I dont see how it could be improved upon.RockyMtnTitan said:
However, CaptFDU's looks way rich (way richer than any other Titan I have seen on here). I dont think there is anything you can do without re-programming the fuel curves, but a reprogrammer doesnt exist yet (as far a I know).

Ran my Titan bone stock, CC SE 4x4 Off rd. pkg, BT pkg, bed pkg spare and tail gate in place as well as 2 car seats.
Best run: 15.45@88.71mph
Other vehicle on slip is an 04 dodge ram 1500 hemi QC 4x4, also its best run of the night. When comparing apples to apples its not even close!

My first post ever...I just have one question as of now regarding the throttle body spacer. I wanted to know if it makes a difference in performance and gas mileage??? There is an eBayer that has a few for sale, one of the models is called "AutoXtreme Throttle Body Spacer" for $65.00. the next model is called "Helix Power Tower" for $82.00 and the last model is called "Airaid PowerAid Throttle Body Spacer" for $107.00. Any feedback from these items will be greatly appreciated!!

Stock Exhaust Intake MOD: Unichip
Ok guys here's my dyno in 100F temps using Unichip. SAE corrected. I ran in 3rd gear and had premium fuel and aggressive switch selected (MAP A).
All stock. Only adds are Fram Air Hog and Mobil synthetic.
In a few weeks I'll have a stock dyno run and will be able to compare to unichip runs. I also hope to have the chip tuned for the truck in this time frame too.
For help Uni-tuning can those that have their Air/Fuel runs send them to me by email/fax or post.
Can't wait for 1/4 track run either!
Thanks
Randy

I've got a new best time weighed 5333lbs at time of run. Still box stock w/22K miles, guess I need to change the original air filter. 15.42@88.79mph. Finally traped at 89 on my last run but only a 15.47-poor 60ft(2.371). 15.3@89 with a stock full weight CC 4x4 coming soon! :readclose

I just got back from a dyno day session. Due to the overall diameter (3/4") being shorter and each wheel weighing 25lbs more than factory, they estimated I was losing anywhere from 10-20hp. I was going to dyno with the stock wheels, but I figured I don't roll with them so never mind. No big deal. Anyways, here's the printout of the dyno run.

you milage is WAY to low to be on a dyno imo. get it dynoed again at least around 2,000 miles. should be at the same place. I'm betting it won't be that rich. just my guess...CaptFDU said:I will try to attach a larger pic. The guy that was doing the dyno said same thing about running very rich.

I just made the sig. Sunday...Hawaiianbasshead said:
Actually its a Mr. Grille Billet lay over. Each piece is held on by 4 zip ties...
Thanks for the compliments, when you change your sig, it goes back and changes all of your sig's on all of your posts ever. I had just washed and waxed with meguire's products, and I thought well what the heck, I'll snap some clean pics's. I had yet to apply the tire wet though...

New member here. Put my '05 KC LE on the rollers Saturday...264hp/335tq. Bone stock with 87 in the tank. Maybe a few gallons of 93 were left in there with it. Needless to say, I was very pleased with the stock #'s. I was only expecting 250hp and 300ish tq. Time for some exhaust work!

Strapped her up to the dyno again today. This was my third trip since buying the truck almost a year ago. Thought you all might like to see the progression from almost stock (KN w/ airbox mod) to where I'm at now.
Note that on the last scan, I did a before/after ecu reset so you can see that there is some gains from doing this. I had just done a reset after installing the AFE a few days ago, and have been doing a lot of data logging with my foot into the pedal. So, the little bit of learning the ecu had done, prior to the reset I did tonight, was pretty aggressive...thus a smaller gain...if that makes any sense! The reset gave me my best dyno numbers so far, and this was on my 4th run tonight when the motor was the very heat soaked.
I also logged a bunch of data with my scan tool for all of the runs to send to Ron at ProAuto for the "black box" he'll be flashing for me ( I hope!).
I'm pretty happy with my results at this point, although I can't seem to get my torque above 333 no matter what I do.
Of note--All dynos were performed at the same shop/dyno/operator.
Here's the progression:
*Baseline* Dyno session #1:
Mods: K&N panel filter, airbox mod
HP: 253
TQ: 304
Dyno session #2:
Mods: K&N panel filter, airbox mod
AeroTurbine custom exhaust
HP: 260 (gain of 7)
TQ: 331 (gain of 27)
Dyno session #3:
Mods: AFE Stage II Intake, Airaid TBS, TB Coolant Bypass,
FM cat-back w/ Borla XS Muff, Rear cats deleted
HP: 281 (gain of 21)
TQ: 331 (no gain)
*After ecu reset:
HP: 285 (gain of 4)
TQ: 333 (gain of 2)
Total gains since initial baseline dyno:
HP: 32
TQ: 29
Not bad for a few bolt-ons!
Thanks!
