Yea its because your car is gonna run MAD lean with this size T/B. 75mm is even too large without F/I. Go 70mm, its plenty large and your car wont be starved for air. Kinda wish I still had mine, but I sold it because ill have a dual 57mm soon

its got a tune for it from american muscle. i know that a narrow band air/fuel is pretty much worthless but i put one on it just try and keep an eye on what its doing and it pretty much goes from a little lean all the way to rich but mostly it stays in the middle. when i get on it, it pegs rich. So I dont know, maybe thats why since i put this thing on and got a tune for it, ive been getting crappy mpg.
