Calling all UpRev tuned cars....

bluestyle55 · 02-02-2010, 09:24 PM

Still can't believe how much gain G37Sam is claiming to have gotten with a UpRev tune on a N/A car. (Trust me...I really do want to believe)

Can you guys quickly comment on your gains.

I am starting to get tired of waiting on Cobb to get this VVL crap figured out...so I have been thinking about going with UpRev.

G37sHKS · 02-02-2010, 09:35 PM

why you dont believe??

He live beside me.. and I know his car.. and my car will be tuned soon too.. and there are already 3 g37S tuned at same place where G37Sam did.. all off them got good gains.. Sam got 296 HP the other one got 291 HP.. why?? the answer is bcuz Sam got test pipe. the other dude got HFC..

and dont forget that sam raised his max rev RPM.. his car can rev all the way to 7600 RPM or somewhere around that..and the stock rev limiter is 7200 RPM..

I am hesitant to believe becuase the cobb tunes are getting like 1/3 those gains.

uprev doesn't mess with vvel either so its half dozen of one and six of another...I'm pretty sure the 370z has throttle opening as good as possible unlike the older Zs and Gs which is where more gains were seen on older VQs...

I'm pretty sure the only thing tuners change is your air fuel charts... and I'm not even sure if they mess with the timing yet either... So unless ur a/f is totally out of whack gains will be minimal compared to older Zs.

I have an uprev license from my old g35 and I have yet to get it into the Z. I have pre ordered the LTH and will probably get an exhaust before I use the uprev license in my 370 and I will be sure to post the before and after charts...

I may even put the license in sooner and I still will post.. My only mods now are G3 intakes and Test Pipes.

Well dude.. it depend on the tuner too..

370zdub · 02-02-2010, 09:59 PM

I can see the G37 seeing bigger gains than the Z just due to the nature of the car, sports car vs. luxury performance. I could be wrong but I do believe the G offers slightly less hp from the factory than the Z and a lower Rev limit?

G37sHKS · 02-02-2010, 10:02 PM

^ true that.. g37 coupe has less HP from factory than the 370Z, but not sure about the rev limit.. but even if the rev limit were the same.. the 370Z will still go over a g37 Coupe bcuz of less weight...

LiquidZ · 02-02-2010, 11:27 PM

Personally, I am really liking Cobb, especially after their price decrease.

drZ · 02-03-2010, 12:15 AM

i had the uprev done and i gained about a 8whp gain nothing crazy deff felt the difference though

theDreamer · 02-03-2010, 09:15 AM

Tuning is not an exact science, from factory people have slightly different tunes which is one reason someone might get 15rwhp and another 10rwhp for the same mod. Then when they each get a tune, the one who gained 10rwhp might get 10 from the tune while the guy who got 15rwhp will only get 5.

vipor · 02-03-2010, 09:18 AM

Looks like a 7500 redline to me.

Thats why I am kinda wondering if the tuning or our car can be the way other tuners like APR, GIAC, etc. do it and just create several files with different mods to them. The outcome wont be 100% but from what I could tell on my last two turbo cars it was probably at 95% and only $500. Quick and easy too and new updates were free when you added another mod. They would have a tune for just a CBE, then a TBE, then a TBE CAI, etc.

The gains on Sams car are quite high but let's not forget how lean his A/F was before the tune, he was running almost stoich under full load:

Zsteve · 02-03-2010, 11:08 AM

But with each mod we do, doesnt that make us more and more lean too? If so that means if you have HFC, CBE, and CAI you should be very lean and should gain close to or better than his, right?
