So guys we finally had a dyno run, at minimum boost of 5 psi we managed to pull 350 BHP on a mild map producing a lean output, means with a minor retune we can push another 20-30 hp at 5 psi. Now since the turbo i am running is a dual ball bearing 1100 HP rated PT6766 by precision, these turbos dont manage to pull anything at low PSI rates means the response is very low for such hugely sized turbo at low boost.
with boost levels at 14 psi i have my fingers crossed for atleast 570-600 BHP. Due to personal problems my tuner is out of town so the wait is for him.
