Well i kind of find this weird and I was wanting yalls opinion...I took the AFC out and put a 4000 governor spring in and it smokes less than before. The fuel screw is the same and everything. What does everybody think is wrong? But there is a good side,I reved to 4000rpm ONCE today and that thing sounds wicked!!:peelout

At WOT your not giving it any more fuel than you were before, Just more air from your turbo = less smoke

with no intercooler your egts will prob melt down head. but a aftermarket turbo would help smoke. and a 5 speed. or tight convertor. under load builds smoke. BTW just so you are aware smoke is bad. it should only smoke a few secounds til boost hits

i don't think i'd rev that thing out to 4000 very often, you'll float the valves. i can get mine to 3800 with my 366 spring and i cross my fingers when i hit that.

I know what you mean by smoke is bad but i was just asking that question because with no AFC i figured it would smoke alot more. but i guess i was wrong

well no afc is just full fuel. when you floor it you are pushin those rpms high which is making more flow from your turbo. this actually sounds like it was a good modification
