75mm TB Hurting my low end more than helping my topend?

[955.0HO]

is my accufab 75mm throttle body hurting me more than it is helping me.

i have heard from others that it takes too much low end, which it does feel like to me. but i can defiently feel it in the top end that it helps(either that or the plenum)

should i put the stock TB back on?

With 4.10s you likely don't stay in the low end of the RPM range for very long. No, I definately wouldn't put the OEM one back on. A 70mm might have been better (and this is exactly why I went with the 70 on mine - I was afraid of what you are describing), but I think the difference is minimal. Take a look at the plenum shootouts over at www.modulardepot.com - complete with graphs so you can get a good idea of what a 70 will do as opposed to the 75 that you have.

U have enough correct mods to warrant a 75 mm, but maybe a 70mm might work better unless ur superchrging a some point.
