can some one tell me the optimal size throttle body to get

Your stock one. Accufab makes I believe a twin blade 60mm, but there have been enough horror stories about messing with the TPS and such that have kept me far away from even bothering with and saved my cash for something i'll feel.

If you decide to take the plunge, let me know how it goes.

it's not really gonna have a big effect other that give you a tighter throttle feel....but if you do it go with the twin 62mm from accufab

I love mine it wasnt hard to setp up. Our tp sensor has limited adjustabilty. If you have a way to measure the staic voltage it is just easier to get it adjusted quicker. Loosen the 2 screws and twist it I dont remember which way sorry but one way or the other you have a 50/50 chance of gettign it right the first time. Twist it tighten screws fire it up if idle is high shut off car twist it the other way tighten screws seems simple enough. I have a Predator I measure the voltage took me a while to find in in the Predator menu I believe it was in the transmission menu. Generally the voltage has to be less than 1 volt they say for best results between. 91 - .95 volts that is about 1/10 of a volt. Since the tp isnt adjustable from the factory but can be twisted enough and tighten down to get this voltage so I dont see why others have had a problem installing a updated Accufab unless the tp was damaged during installation.

Our factory one is 57mm the Accufab is 60mm which one would you rather have? Since I bought mine for $230 used I will not be installing the factory one anytime soon.

I put in pictures but they wont take so I will put up links to the pics.
