I don't get that belt squeal anymore after I stop do u get the belt squeal during the run?
have you done the throttle reset?
when you last ran was the temp as hot as it is this month?
19 lbs of boost sounds like what the code 3 can put out.
try to add about 2 gal of 100 octane gas to just under 1/4 tank.
mph can also be lost by tire spin at the line. did the et drop?
