What have the stock/after 06 MT#'s been?
I'm doing the Mrev/spacer with Nismo exhaust and wondering if a tune would be worth it. I've only seen a few dynos posted and one was a turbo; the other was ~5hp/tq gain. Is there a healthy 15-20 bump somewhere in the usable rpm range? How does the throttle sensitivity adjustment factor in (quicker rev)?
Is raising to 7400 ok?

post your results guys in case Uprev does not respond. I'm more interested in pk gains than top end,
ps I'm in Austin

 

With my Utec tune i got about 7+hp and 7+tq to the wheels.

 

Ive got a post somewhere around here but I picked up 12rwhp and 12rwtq after my tune. Im in austin too if you wanna meet up and discuss things

 

To be perfectly honest we've haven't tuned a lot of NA Zs. The majority of our Z tuning is FI. We tune NA Titans all day long, but the Z crowd that is willing to spend the $$ for HP seem to go FI more often than not.
This chart is from a Z running:
93oct
Ultimate Racing High Flow Cats
NISSMO Intake
Plenum spacer, 5/16, motordyne.

 

This one was running:
Pop charger
Plenum spacer 5/16
Headers (megan racing)
Resonator & Test pipes (Megan Racing)
Injen SES dual exhaust
Magnaflow x-pipe mufler.

 

That second one is also an AT not MT.

All before and after pulls are done after a 30-45min cool down period w/ a constant coolant temp (@ idle) of 86-88 deg C.

Thanks for the replies Jarod. I hope those were 05 or older Z's, if not I should forget about NA and start saving for TT.

 

What's so critical that you need a TT for? What are you using your Z for? Daily driver? Track? I'm almost certain that you probably have not utilitized your Z's full NA potential yet.

 

The AT was this guys 06 ^^^

 

nice numbers for an auto.
If it were 6mt it would probly be near the 270whp range im guessing.

lago350, keep it N/A and just get wait to get her tuned untill you got all the mods you plan on getting or untill you start getting really deep into it.you'll make plenty of power.

 

I use the Z for a daily driver (when it's not nice enough for one of my bikes).
I have some really nice curves to eat up on the way to work. I think my main problem is not yet knowing how to drive this car. Most of my previous sports cars were modded vettes with monster torque. I'm just starting to realize that I need to keep it above 4K to begin to get in the motor's zone. Everytime I ***** about this car's power I get on it at highway speeds and I'm amazed. I'm open for suggestions. Should I preload a couple of K before I launch when I want to get up to speed quicker. I was planning on the MRev/spcr and tune as my last mods and hoping for ~ 260hp/240tq at the wheels. I'm not even interested in that much of a bump, just more lower.

you still in Iraq Rev-em?
GolfinZ - come on out to Lago Vista and we can shred 1431

 

I auto-x my Z about 1-2 times a month. Trust me, our Zs have plenty of torque and top end power. During my last auto-x two weeks ago, I posted faster times than several STis, an EVO, an M3, a Porsche C4S, a couple of Lotus's, and even a Z06. And that was right after my UpRev tune!!! Believe or not, auto-x is not the Zs strength. You will learn to really appreciate its power & handling in the track (road course), which is where our Zs perform its best.

 

Hey now that sounds fun!

 

yeah still in iraq but mabey not for too much longer.

 

Hey Jared.. Quick question.. I know you told me before but it slipped my mind. I wanted to ask if you pull my utec for example and tune the ECU will it recognize boost?? Im running 16psi.. Thanks

A few others on here wanted to know this also.. so this will answer..

 

Gods Speed Rev-em!

Mthreat & Golfin - pm me your cell and we can arrange to meet up in a coming weekend.
