I had my car in the body shop & my engine no longer behaves like it did prior. Different oil pressure, found things disconnected. Lower HP. I want to make sure I have the same stock 14k mile uprev that the car went in with. Also shop employee wanted my car & own a G35. They had it over a month and had things apart that had nothing to do with the repair. Can I verify SN to VIN or make sure it is a Uprev etc?

 

if that is the case that guy is going to hell. you should definitely try to get to the bottom of this.

 

oh boy...

 

Dealer may have the serial number. UpRev is tuning software, simple to check. Just connect your UpRev cable and make sure your map is loaded
