Hey !,
First timer and sorry for rehashing but due to working constantly looking for some sound advice. Have browsed frequently and followed forum advice in general so far, heres my last mod delema, So far on my 03 gt stick car I have done , Hurst shifter, 373 gears,K&N cai, aluminum driveshaft, ford Racing stainless steel shortys, Bassinni catted mid pipe, flowmasters and now want a intake pelinum, throttle body & tuner. Was thinking of going to Brenspeed but need to know what throttle body set I should use, can my car handle the BBK 78mil or should I stick with 75 or 70 ? Not looking to do much else to the car at this point and want to keep it a summer driver. So 78, 75, 70 and sct or Diablo ? Thanks to all ! Jeff

I you are just going the bolt on route, i'd stick with the 70mm. Anything beyond that i'd do the 75 or 78.

I went with Accufab simply because i wanted the highest quality.

Went with SCT custom tune from Brenspeed, now should I get the Trick flow plenum & 70mil throttle body? wondering if itwill be noticable or should I just skip it? Thanks

It will be noticeable but nothing neck snapping. The car will feel a lot more responsive but not necessarily faster.

Other than slightly better throttle response, i didn't notice anything.

Wow, someone actually doing research, not too bad on the mod choices. Yeah pretty much your choice, 70 is all you need, anything high may be a little overkill, but dont think either difference will be dramatic. As for tuner, I have diablo, isnt bad at all, but i have heard of a couple things on the sct that im not sure i have on diablo, and sct i think is a little bit more reputable, but again just a matter of choice, nothing terrible about diablo.
