TPI vs. Single plane EFI manifold, anyone dyno?
I am really starting to hate my TPI. I am running aftermarket Accell base and TPIS large tube runners but it has SO much low end power and not much pull up high that it is worthless. I can't grip at low speeds and the car is a dog at high speeds.
I was wondering if anyone has upgraded to a single plane intake and done a dyno of before and after for comparison.

i have a 86 305 tpi and it hade 180 hp at the wheels, i added the summit tpi cam, lifters and springs and im building a single plane intake now, but dynoing it is going to be tricky because i added a turbo also but will post # when i get i on the road
