Got my car tuned with UpRev
 

So I get a call from a local UpRev dealer saying they think they might be able to tune my car (been hearing that for the past year now). They ask me to come in and have my ECU ROM file read and sent to UpRev in attempt to have it cracked and what do you know...

A few days later I get another phone call saying my friends G37 (Gulf Spec) was tuned flawlessly! I book an appointment and get down with that!

My current mods are: Stillen G3 Intakes, FI Test Pipes & Catback and UR Crank Pulley. I'll let the pix do the talking now:

And we're ready for action!

Almost an hour later, the tuner was done. My main issue of running too lean was solved thankfully as you can see.

According to the tuner, unlike American Muscle cars which he tunes a lot, our VQ's barely respond to changes in AF ratio in the power department, but reducing the AFR to 12.5 ultimately allowed him to push ignition timing even more which was the key! I honestly was not expecting that much of a gain but that tuner seemed to know what he was doing from the first phone conversation I had with him. My maximum power came in at 7200rpm before the tune, after messing with AFR & Ignition Timing, the car kept pulling up all the way to 7600rpm!

Here's a video's of both runs:

And finally, the dyno sheet:

Before the tune, I put down 262whp @ 7200rpm & 289 N.m
After the tune, I put down 296who @ 7600rpm * 321 N.m

I was very impressed with the numbers, but those don't mean anything if my butt dyno doesn't confirm. So I took the car out for a spin and all I could say was wow. None of the mods I ever installed ever felt like that after their install, you can feel the gains from really low. Even on 5th on the highway, it's takes less effort to speed up. On 1st, don't even dream about driving in a straight line on tarmac. We went Auto crossing today and it honestly felt a tad harder to drive due to its tail breaking loose with every blip on that throttle. I cannot be any happier to be honest, not without boost at least lol

Another cool trick they did was upload a valet-map which you can cycle to via cruise control. The valet map basically limited the revs to 3k and the speed to 70kph (43mph) I recorded a ghetto video of that:

Don't waist your time on preloaded maps or maps that don't tamper around with your ignition timing. UpRev is the way to go!!

My G is back to life!

34HP and 32TQ gain from a tune and nobody is commenting on this?

LOL well it has like 50 views or so, I just thought I'd share since it's the same engine

good deal man !

Awesome gains! Not what I was expecting at all.

Yeah same here wasn't expecting numbers in the 30's to be honest..

As I started reading, I was guessing ~10 in my head. You blew my mind sir.

I'll pass that message to the tuner :tiphat:

That's freakin awesome man... I can't wait to get mine tuned... I'm sure its runnin' lean right now... I was leaning towards the Cobb but these results are really nice...

I'm sure it has a lot to do with the tuner though. I need to find someone that knows what they are doing around here.... Still have yet to do that.

So what does the Uprev tune do now?
As far as I was aware it can really only mess with AF mix, Uprev has not cracked VVEL nor timing table.

I havent read anywhere about someone cracking the VVEL but UpRev can mess with your AF and Ignition Timing. I was running around 34 degrees BTDC at high rpms before the tune. He wouldn't give me the after tune though lol

Sounds good, I am not sure if any has cracked VVEL but just wondering if that contributed to your awesome gains. Guess not, which makes them even better. :D

Wow, now this is more like it! I've been very disappointed in the gains from tuning until this post. Hopefully more tuners can pull off those types of results!

Oh snap. That is what's up. I just hope I don't have to go to Canada to get that kind of tuning done, lol. It would be a looooooooong drive.

Yeah I really wouldnt mind someone messing with my VVEL especially with the Long Tube headers combo
