Super tuning car runs good shooting for great

I do have the cam assortment. I haven't tried messing with it. I think you've got it backwards with the power valves. the 6.5 opens at 6.5 which it drops to less than that on take off adding to much fuel when the throttle blades are barely open. The 4.5 wouldn't open Intel the vacuum drops below 4.5.

It runs like a skulded dog getting after it. Doesn't bog one bit.

The accelerator pump is adjusted correctly.

I'm thinking the pump shot isn't the issue under the light tip on take off throttle situation.

I need to hook up one of those air fuel readers. I bet it would be super fat for that split second when the vacuum drops.
