Fastman Throttle Body

I received the fastman throttle body today, cannot say enough good things about it. The work is top notch and there was an absolute difference in performance. fyi: i already had the Henessey CAI installed.

here is the difference that i noticed. for science sake i was not trying to get the best 0-60, but rather a consisted one. so my stock run i just put the truck in sport mode and simply slammed the gas. i did not do manual shifting as this might alter the 0-60 time and be less consisted. so this morning in 46 degree weather i did 0-60 in 4.6 with no wheel spin and maybe a slight chirp of the tires 3 times. engine temp was 190 degrees.

i installed the fastman throttle body, drove the truck 3 times through out the day for short errands to get the truck accustomed to the TB. I then went to the same road, same, direction. and did 3 more 0-60 runs. engine temp was nearly identical 190 degrees which seems to be operating temp. i again put the truck in sport mode and attemped my first 0-60, epic fail, i ran a 4.8 and tires were spinning as well as traction control light came on. the truck then missed the shift and fuel cut off kicked on.

i then ran the truck a second time same road, etc and same experience. for the third try i kept the truck in sport and just shifted manualy. the truck ran 4.3 which is by far the fastest i have had out of the truck. there was still excessive wheel spin and traction control kicked in again. but there is no question the TB added significant power and second i am confident i could get 4.0-4.1 0-60 with the 2012 jeep.
hope this helps others in making a decision. i have posted 2 photos demonstrating the difference in the bore of the stock vs fastman TB.

Re: Fastman Throttle Body

Is that the 87 mm TB? Ported 87mm all the way thru or that taper bore design?

Thanks man! You running a tune of any kind? Only thing that has stopped me is is the TB just leaning your stock tune up or are you actually gaining hp. Dont want to spend the money when I can lean it up in my tune. Its gotta do something though, all I see is the 85mm on his site did you have to ask for the 87mm?
