well from what ive been reading over the board for the past few months.. I was wanting to change my pulley to the 65mm chicane one on my series II..Ive heard over and over that you need to upgrade to 42lbs and a 90maf aswell as a svt pump....So today i call joe at chicane to order my ripp kit and we get talkign and i tell him how i want to get teh puley soon but still need the others parts first ..he tell me i will not need the injects or the maf..stock is fine..he said aslong as i have a safe tune i will be fine if i was planning on running like 380 to the wheels yes but it will only be prolly 335 so he says its not a biggy.....just curious what you gusy think..is it in the tune or do i really need those other parts???????
