hey all. i'm thinking about getting a spacer soon and was wondering if i need a tune with it? i got intake and exhaust right now and spacer in near future.
thanks

 

depends on how big of a spacer.. and if you're going to get high flow cats later on-

if ur gonna stick to the spacer and nothing else for a while (1+ years) then you could opt for reflash or whatever piggy back computer to optimize your engine and take advantage of the benefits (ign timing adv, better a/f, throttle control, higher rev limiter) it'll make for a more enjoyable car.

 

i was thinkin about gettin the 5/16 spacer. thats it just those three mods. any1 else?
