UpRev tunes...

[rocket69GTP]

Been doing a little research and found these cars run a little too lean for their own good and found a place in hawaii that does the UpRev tuning. My question is, does the ECU in the G37 catalog when parameters have been changed or could I get the car tuned, reflash the original tune back in the car and take it to the dealer without them finding out about it? Thanks in advance for any feedback.

Pretty sure you have to pay a pretty penny to modify a OBD2 ECU, say like 20K!!!

I would think that when you reset the ECU (remove power) it should revert to factory settings.

You can get the Uprev (Osiris) flash and it is unnoticeable.

If the dealership has to reflash the ECU ever, it would erase the tune though.

Additionally, you should be able to set it back to stock at any time that you want if you get the software with your tune.

I like the looks of that tuning package, and very affordable, too.I may have to drive up to Austin and check these guys out, see what theycan do for my oh-ten G37 Sedan. That'll help me get past the break-in!

Anyone have any actual experience with these tunes?
