  1. I finally choked up the $150 to get a Summit Racing brand 75mm Throttle Body. I am actually fairly surprised; I didnt think it would be worth much rwhp compared to the stock Throttle Body, but it is actually pretty amazing. I guess the stocker was chocking out my blower cams. Now I cant get it to hook up at all in 3rd. Im pretty happy with it... also my boost went from 11 to 11.5 psi (in the winter months on a 9 psi pulley) from just the TB swap. I need to put it back on the dyno to check my A/F... hopefully that will happen before I leave, but if not then I will talk to pro-dyno in SC, since I will be in South Carolina in April...

    Isnt the coveted mustang week I keep reading about in these forums located at myrtle beach (sneaky, tank, etc), or am I off?
  2. I installed a Accufab 75mm T/B when i installed me 2.1 KB. I also did the entire KB CAI and LMAF. That combo brings to me 11.5-12PSI when its 50degrees or below.
