Fastman vs BBK throttle body???
Which one performs better? The fastman or the bbk 85mm throttle body for stock truck???

You won't be able to tell a bit of difference between the 2.

If you are stock, you won't see any difference except in the very high RPM range. I personally prefer the BBK 85mm just because most of the Fastman TBs are only ported and maintain the stock butterfly diameter (unless you specifically ask for the larger butterfly).

Has anyone else have input between the two? It looks like one is $220 and another $400. I would lie to know if there is a difference in performance.

I have the Fastman ported tb. I have the one that is comparable to the BBK and is a full 85mm straight down. I never owned the BBK so I have no input other than the fastman ported tb is cheaper. Also look into Moes Performance, he has ported tb's for sale at a good price!

I'm new to this forum, and I need help with my throttle body.

I cleaned the throttle body with brake parts cleaner and now it's messing up a lot.

The etc light comes on about every twenty minutes while I'm driving and my truck idles higher than it's supposed to.

I wasn't sure which thread to post this I just took a wild guess. lol

The reason why the BBK is so much more expensive is because it is a new cast TB. The ported TB's from Fastman and Moe's are ported Mopar TB's.

Also, without custom tuning, many guys with the BBK have thrown a high idle code.

I went to the dyno today and picked up a whopping 26hp/24 ft-lbs by installing Moe's 85MM TB. It exceeded all my expectations. I e-mailed the dyno chart to Matt at Moe's about an hour ago.
