accufab throttle body

[SVTWHITEROCKET]

Does anyone know if you add the accufab throttle body if you need to tune your truck for it thank you Harry

 

[Robert Francis]

If all you did was add the TB - no, you won't need an additional tune.

 

[fruhdaddy]

no, but make sure you adjust your TPS properly

Are there any power gains from a single blade TB alone? I've found mixed opinions. How do you adjust the TPS?

 

[Jroc]

no, but make sure you adjust your TPS properly

Here's my opinion.

Aftermarket TB's have their benefits, but sometimes they can be hit or miss. Some work great and some give you driveability issues even when comparing identical TB's. IDK I never had luck with aftermarket TB's on my Mustang. I couldn't get my BBK 75mm TB to ever work right on my old 99 GT even with a tune. Again so do have good results with them and some don't. On a Eaton truck I personally would just go with a ported OEM TB. You can port it yourself for free even you just have to know what you're doing, but it's not that hard and there's actually quite a lot of material that can be removed.

I agree. I ported my stocker and loved it, planned on going Whipple and grabbed a Accufab SBTB for $100 in the classifieds so I couldnt pass it up. I feel no diff in power at all with my mods in sig. Im certain with a Whipple or KB there will be.

BBK is junk. If you barely have mods that would benefit from a SBTB, unless it's a great price (used most likely) then sure. Buy it new...then no. Ported stocker will work great for a mild modded L. plus easy to do if you plan to port yourself. Your plenum and SC are a bigger restriction than the TB. Port all three, best bang for your buck.

+1 i concur

I have a ported throttle body on a 12.3

Ported my own was pretty easy

I also cut and grind the throttle blade screws too.

I was eyeing the twin-blade BBK unit typically found on summit racing-

I keep reading about others "porting" the OE one but no one has posted details on how this can be done at home.
