No matter what I ever did, 39 psi was allways best. Try changes at the track. Three passes, change, three passes, change....

i will run it back to 39lbs. and try it with the new manifold/heads. its just that i bought this new adjustable regulator and thought it was going to be of some use. the stock regulator was always dead on at 39lbs. and a lot lighter, just not as pretty.
