I ran across this while doing research for something else http://www.turbocity.com/product_inf...roducts_id=602. My question is has anyone used this & what were the results ? Postive, negative, or nuetral.

Three days & no reply's

I dealt with turbo city about 4 years ago when my 92 was TBI. I bought a bored out TB and had to put a AFPR in it. It worked out well but knowing what fuel pressure I had was a bit difficult. What I had and what you have on the link are different. My guess is this is their updated version. Looks pretty good from what I can tell. I will atest for the great performance I got out of the TB though. My throttle response became instant and they gave me good tech support.

I'm building a roller cammed 383. I plan on using a 454 throttle body with the the stock 350 injecters. With higher fuel pressure this should work ok. I'm trying to avoid running rich at idle.

I'm sure if you give Turbocity a call they'll set you in the right direction. I had a strange fuel curve that I couldn't work out for whatever reason. It was rich in low rpm and lean at high rpm. I eventually just went TPI when I got a donor car.

G.M. used to make a factory vafpr for the 454 tbi but they have discontinued it. Mericruiser used to make one also. Does any body know where I can find one of those?
