i think your problem lies in your choke point, what does the modded secondaries neck down to just after merge? i think you should run a 2.36 choke on them.

Could be but not prepared to fix it as I will be getting a header. Just thought I would dyno b4 and because the stock secondaries were dented I replaced them.

The Formula is simple and easy but you have to be willing to follow.

Thanks, but Thor has higher aspirations (where power is concerned) than I do. Even then, there are different roads you can take to reach the same destination.

You must at least make the parts work together. So that 3" exhaust usually pushes power up rpms. The longer runners? They don't.

Getting the parts to resonate at an ideal rpm is what is going to wake it up. Even if you get in the ballpark it will still make gains.
