perhaps yall can HELP and not bash.
copied/pasted from my local GTP forum
ok so the dyno tune went well..kinda. im gonna try to sum it up so im not writing a story, but theres alot to say.
the tuner HATED Will from overkills tune, said the timing was wayyy to high and dumping way too much fuel, said i wouldl have popped a piston soon due to having 4-6* of KR on the 3.4
i have a boost issue, boost was 6 psi one run, 11.5 the next then 5 the next. belt slip? prob not. tensioner? perhaps? bbv? they think it is.
Its NEW from Eaton though? the linkage or w/e you call it wasnt depressing all the way down they said, so we held it down for a couple runs with a scerwdriver and sure enough, 11.5psi peak, 9 psi throughout. he got rid of all the knock and set the A/F in the high 11's. the car only put down 214 hp/229 ft lbs on the mustang dyno.
was also told my K&N intake is sucking hot air in and they recomended Thrashers "cold" air intake or similiar and he said he had a open cone on his GTP and dropped IAT temps alot by switching to Thrashers..idk. this guy seemed to tell me opposite of what everyone on here teaches. he also said 12* of timing at WOT is what these cars want, not 19* which is where it was. idk really what to think, im unsure if i came out on top or not? def gotta fix the boost issue, i got a spare bbv kicking around i gotta troubleshoot.
ported blower was not installed at this time
car ran a 13.5 @100.88 in the 1/4 as well
