Re: Upgrade to SNS StIV chip and 3.5 bar FPR??? (G60_Likes_2_Break)
The autothority makes pretty good stage II-III power. There is no difference in program for the 260 cam, it is a very mild cam.
You never stated what cam you have, so unless you have or install a stage IV cam, you won't notice any real power gain.
Your car will just run real rich = Not good!
Don't waste the money. Stick with what you have until you put in an aggressive cam, then upgrade the fueling (chip/FPR)at the same time.
That's the whole idea.
