your not gonna get much from a d17 if you only go bolt ons cuz to tell you the truth, our engines done respond too well to bolt ons. if you wanna go power, its best to go boost or K series. thing is, if you go boost with an auto, you'll never know what can go wrong since you cant shift at desired rpms. im auto myself, and i have a turbo not installed yet, but if i were to boost, id change the transmission to manual while your at it. as far as i heard, you can get like 12-15 horses more but your gonna be spending at least 500 dollars + ( as far as going N/A )
yea they have those overhaul kits from..tsi? im not sure.. but theyre basically new stronger parts..theres people boosting about 9-10 psi on auto trannys but theyre able to handle it. i herd auto trans can handle only 7psi max..
