My mate has 89 GTE (same as me) and mine pi$$eS all over his. His is chipped and thats it. Now... he wants to buy something to try and get his to keep up with mine. I say a power boost valve would make the most difference (advice from you guys) and he says a K&N induction kit or an S.S manifold would make the most.
I told him not to be cheap and get em all.. but hes a student LOL! (no offence students).
So who is right. Power boos valve OR K&N OR Manifold?
