Back from the Dyno, What do you think
I have a TT setup, running twin GT28 turbos @ 7.4 PSI. The car has a vey safe tune on it. The car put down 381 RWHP and 437 RWTQ. The car sits at about 11.4 to 11.3 air/fuel and at the top end the boost creeps down to about 5.5 PSI.
Also my torque curve hits 400 RWTQ at 2500 RPMs and doesnt drop below 400 until about 5500 RPMs
We calculated that about every pound of boost will give me about 20 RWHP
Whats do you guys think? Thanks for the input

Wow, that seems very weak. Im putting down 492 with a single turbo and 7# of boost.

I think taking about .5 AFR out of your tune would put your numbers up quite a bit. The reason your boost is dropping is becaue your so rich that your EGt's are dropping to the point that it can't keep the turbo spooled.

Can the chart be altered at the shop? My car actually made 515tq at first and he detuned it to keep it together. Jeff at Hellion is putting my car on their web page he personally knows my tuner and ask me if he could put it on their. If you dont believe it I can foward his email to you.
