Ok, this is a 416 10:1 cr, cam is a custom 233/248 .629/.600 115 +3 LSA, ported ls3 heads by tsp, the turbo kit is a AGP twin turbo kit with twin 5858 comp oil-less turbos and the big intercooler, AEM water/meth kit on 100% M1, boost controller is the GFB3, all going thru a built 6l80 with a circle d 3200 triple disc converter and a 3.70 gear. I was expecting to make near the 900whp on this combo but it wouldn't even break 700whp last dyno pass was 670whp, the car idles and drives perfect no missfires or noticeable stumbles and part throttle feels really good.
Since this is my first turbo tune i would like to see if there is something obviously wrong in my tune to be so low on power.
this was on 100 octane gasoline

The MAF stopped working while i was doing the SD tuning and i haven't fixed it but at this point i feel it shouldn't affect power.
