Any tips are welcome!
Currently my under load manifold vacuum is 0" at 5600 and 0.8 at 6300.

545 hp/540 tq rear wheel would be my guess
flywheel numbers would be about 80 hp 90 ft lbs higher
yeah a good tune will boost the numbers, but I'm thinking average and a few restrictions

I get 3 pulls in the session so my intention is to do the first 2 w/out any air cleaner then I'll see what I'm losing from it.
Cheers.
