If you are running Uprev software and if you take the car over 400whp, you absolutely must buy an upgraded MAF sensor ($350 shipped from Uprev) or the car will forever run lean.
Also, just lol at Hill's pricing. Holy christ are they expensive.

I asked out of curiosity and here's what they quoted me for a custom tune:
-$1050 for tune (5 maps)
-$60 shop processing fee which you can cut in half by paying cash/check
