guys i got the revco 60mm tb from aaron (phlatcav) a while back. For some reason it feels as if my low end sufferd some what.... my mid range and top is great but low is just crap.... feeling anyway i may be imaging it but it feels slower at accelearating..... Anyone else have this issue? Also before i installed it you can put it up to light and see a hair line gap around one side of the plate but not both.... my car idles just fine and i dont have any lights or nothing so i just wanted to know if anyone else has this issue...... thanks guys...

60mm TB?

That's pretty huge for an NA car, you've pretty much killed your low end due to loss of volumetric efficiency.

The velocity of the air coming in is actually a lot slower than with a smaller throttle body.

Your top end pickup will be better of course, but at the sacrifice of your low end. so yeah. This happens a lot to people.

Yup,

Esp with the performance mods you have.
You've complimented them with the larger tb.
Which is how it works, because you're car wanted to be in mid to upper range now.

But if you're a granny driver like me, the low end loss takes getting used to.
