Whats everyone seeing for boost at 3/4 - WOT with a "race" tune? (stock fuel) with the TC locked 60-100 I seen a max of 45 psi normal? and 1375-1400 egts.

I don't know if its just me or not but, once I turn off T/H to shift into 6th and lock TC at 60, it feels like it falls on its face then starts to pull slightly? truck holds 24.5K RP.

Other than that the truck drives excellent has a strong bottom end just trying to figure out if i'm in the norm for the "top end" power range.

TIA.

I have gotten my old one to spike over 60 before in 5th read from my ISSPRO gauge, but pushing one beyond 45 psi is out of its efficiency range and ruin it over time.

Nope. No one told me that. So I can't ever use my top gear? That'll really blow going 75.

T/H is basicly a T/H and OD OFF/ON button. Use T/H below 60 once over 60 click T/H off and boom there's 6th gear. Go below 60 click it back on 6th gear is locked out and the shifts are extended to help keep the heat down.
