They said the AF was a little rich top end hense why i was losing power.

 

Bring it over and we will put it on a Dynojet and see what it does. You need to add some timing as your torque is falling off to soon. Based on your mods and boost that number is a little low.

my graph does a similar thing, i have a large street port, running 14 psi, the boost holds strong all the way up to 7500 but power and torque is dying off way early. The turbo is a T4 GT35/40 P trim with a 1.15 a/r turbine and a 0.72 comp side.

There is plenty of fuel, inlet pipes are all 3 inch, exhaust is 3.5 inch straight through, i'm using an XS power FMIC, the 4 inch thick one and the tuner thinks thats causing a restriction.


What do you think? Its the black run and RW power not flywheel

the red and black runs are with an FC and FD Plenums respectivly, and there isnt much in it but the pink run is a completely different engine, different turbine housing (0.96), much smaller ports and series 4 turbo low comp rotors. all still seem to die off at about the same point, the only common factor is the i/c.
