i did read that a hypertech tuner makes the ltfts back to what they should be reading, dont know if that is 100% correct or not.
The Sport programmer has an option specifically for the Cobb SRI. It will correct the MAF calibration, which will bring your fuel trims back down closer to where they would be stock.
^^you do realize this is for a speed3, not a regular 3 right? And how can he calibrate for something custom?
Ok cool, thanks Chris for the help, looks like when im ready to buy my next thing for the car the hypertech will be next.
i would have no idea what i would be doing with either one of those tho, i know the hypertech is plug in and tell it what you have and there it is. Does the ap or sb give you instant hp gains like the hypertech?
Does it also modify the fuel trim if you only have a custom exhaust with stock airbox?
