Tune a stock 04 GTO
I was wondering if any one has/had done this before?
I was thinking a 93 octane only tune and to enable lean cruise, would make some noticale changes. It seems other cars get some gain's from handhelds canned tunes or on a dyno.
Lastly anyone do this sight unseen or in the Atlanta area?
Thank you
It seems that someone got good results out of a G8 and their were some other posts about some cars getting decent results from stock tunes.
$400 that would be worth it, considering the current cost of gas. I was thinking maybe someone already had a good stock tune and would sell it for less really.
