    exactly, same tuner.

      Donno if this helps but I did 330whp @ 14 psi with intake exhaust at robins, after that, i got z32 mafs and the twin turbo divided pipe, did 350whp at same boost. Now im doin 582 whp at 22psi with -5 turbos.

        this actually help! the divided pipe has been proven on the same dyno to produce about 10whp at stock form. so 10whp for the Z32 maf could make sens.

        do you guys run the plastic adapter for the maf or you buy complete z32 air intake system?

            I use to work in a fairly reputable tuning shop here in Perth Australia called Xspeed. We found that the MAP sensors supplied by Apexi in there power FC kit (3bar), would limit the resolution somewhat when tunning higher HP/higher boost engines.

            After a bit of research we found out Trust do a 4bar sensor which comes in their boost control kit. Managed to get the part number of just the MAP sensor and ordered up.

            To our suprise they use the same connector as the map sensor supplied by Apexi, Just 2 of the wire's are around the wrong way. A quick de-pin/re-pin and we got the ball rolling.

            We now have 2 fairly wild animals running twin Trust 4 bar sensors with their power fc. One is making 680hp on twin low mounts (GTX2863's) and E85, and the other is still limitied to 19 psi (because of waste gate spring) but still making 550hp (HKS T51R) on pump gas. Both cars are 2.8 strokers.
            But a 3bar MAP is good to 29psi, what would be the point? If you are going for broke and running up to 40psi then I could see the point. Really, if you aren't making the power that you want at or below 29psi then your turbo setup is way wrong. A 4bar MAP has less resolution (not more) as well so that ain't helping either.

            This is way OT but I though I should point that out. I am making a solid 850fwhp at only 24psi, still got another 5 psi to go before I'm butting my head against the MAP limits.
