So basically I have fitted a dbilas manifold and notice a real lack of power until I hit about 4500rpm. I seem to have a slight flatspot at about 2000/3000rpm.

Any advice? Or should I just fit rod bolts and raise the rev limiter?

Has anyone had a new manifold and a remap prepared to comment?

A 4-2-1 manifold will help bring the power band back down a touch mate.

What will it bring it down to? Would a de-cat make much difference?

What about a remap before or after a 421?

Do everyting you want to do then get the remap last, then you know everything is working together as best as it can
