Have any of you guys ever used the Q45 throttle body? It seems as though it might make the gas pedal overly sensitive...any thoughts? If I only open it a half and its flowing t he same as wide open on a stock 60mm wouldnt that make the engine respond oddly? My setup is as follows:

Hks 264 intake and exhaust camsPorted/polished/cced head(not finished yet)Titanium Retainers and upgraded springsGT28RS turboNo catsThe intake will either be a greddy s13 or the O2 racing550cc injectorsHKS fuel managementZex direct port nitrous setup(only at 50 shot till i get my shortblock rebuilt with better rods and pistons)

Im really looking to hit around 350-375 on the ground with little lag(no NOS)

Oh and btw this is all stuffed under the hood of a 1980 MGB Roadster lol.

That would actually be a bit of a help. cause its hard to get rue 100% throttle on the 60mm TB. They even make bigger pullies for the SR so it gets to open throttle faster. You could try getting a smaller pully for it so it takes more pedal to open it.
