turbonetics 66p to 70s swap

[pressured]

how much power could i expect to pickup running 24 to 25 psi? how off should i expect the tune to be with this swap if at all?

I went 114mph in the eighth with a 6680 @26psi and a hyd cammed 233ci GN1 headed engine. Imo you should be able to get at least 130mph out of it at 25psi with the p-trim. If not id take a closer look at the tune. 135+ with the big ex wheel at 25psi if the combo and tune is there.
