Can you tell me more about the Uprev tune? I looked at their site but it wasn't entirely clear to me what the process is. Do you actually need to take your car to somewhere that has a dyno and have them tinker with things between multiple runs or what? The search tool on the site also didn't find anything at all close to me (Seattle area).



It's also notable that the FI exhaust with carbon mufflers is 41 lbs versus the stock Nismo exhaust which is 66 lbs.

If you look at the sheet we had to stop the baseline pull early because of the fact that it was running too lean. So the base numbers would have been higher if it was a complete run.

Uprev software is used by a shop, in my case SpecialtyZ, car thrown on the dyno and professionally tuned to what i have currently on the car.

I'm sure you can find true baseline numbers for a stock nismo on the forum. I did my baseline run with all my few aftermarket parts already on.
