... so it misleads the ECU??? That's not a good thing to do... I could see needing that for a stock tune, but why is it necessary with UpRev when you can make the A/F target adjustments??? ...hate to hear about cats being disintegrated after 3k miles of driving extra lean and not knowing it... :(
 
Just get headers and different b-pipes, that way you don't have to worry about any CATs :redblob"
 
Hey Corry, I got the tranny mod today! Give me a call asap!!!!!!!!
 
Is that the line pressure upgrade? How does it feel compared to before?

There is nothing that misleads the ECU in the Tune or in that ''translation box'' that is used for to communicate with the MAF sensor on the 4in Relentless CAI. I'm assuming it converts/extends the voltage range/readings since you are putting the maf sensor in a different location in the on coming air stream.

The line pressure mod I have is used in conjunction with the transgo shift kit that I have. So what I felt over the transgo shift kit was very noticeable especially when you use the manual shift from 1st, 2nd and 3rd you can really feel the clutch packs engaging instantly instead of the stock slow slipping feel.

The transmission operates great, I have no doubts what so ever that my trans will have any problems now that I have this line pressure upgrade. If you look over at PAPARYNO'S thread about the ''Tranny line pressure mod'', I gave a somewhat detailed explanation on how it works and feels.

Oh and to hell with CATS, just get resonators in place and call it a day, that is IF the state you live in will allow you to not have cats... I'm glad I live in FLORIDA. You guys should see my exhaust system lol its quite extensive and a lot of trial and error to get it to sound the way I wanted.
 
RELENTLESS SUCKS!!!!!!!!!! i m getting tired of calling them and them not answering my call and i leave a message and they never call back!!!!!!
 
Who are you trying to contact there? What's the reason for your call? I've never had a problem getting in touch with them myself...but you could have a little better attitude though. No one answer's your call...so you just say, "they suck". LOL That's how you get stuff done, just call them out till they answer you?

Sometime's it's hard to get a hold of people who are busy all the time??? Like trying to contact Up/Rev, sometime's they are too busy to answer your call, it happen's!

Have you trying calling Harbor Nissan itself???

They have always been good to me as well. Like what gweasel said, try contacting Harbor Nissan and they can get you in touch with Relentless (it's at the same place).

Relentless is a great company to deal with.

Everytime I call Relentless RPM the front desk lady transfers me back to the shop and i either talk to Danny or Robert. Great people to work with. I have never had any customer service related issues with Relentless, even before going down to get my truck worked on, they helped me out tremendously and were always up front.

UPREV is hit or miss with getting in contact with them, its either you get someone or you don't cuz those guys are always busy.

Hey Pryno, what's your best 1/4 mile time?? Surely not that 13.67 with the listed mods?
 
Glad to hear you were able to contact them in the end! :)

This time is in line with my FST times... Not sure what an 80 or 100 shot gets you; but weight reduction and slicks are good for a 13.4
 
i will pull up my ts with a 100 shot soon. just have to find it but I was 13.67 in fst na
