Very successful day on the dyno...I set a goal when I bought the car last summer to have a turbo setup and make 900+rwhp and today I achieved that. We did a total of 9 pulls on the dyno after finally figuring out the eboost2 boost controller settings.

First pull was 637rwhp 10psi ended the run at 6200rpm because it was spinning.
Second run was 669rwhp at 7200rpm 10.5 psi
Next was 722rwhp 807 tq at 11.5psi wheel spin
At this point we started messing with the gate settings also on the boost controller to get rid of the spike once the gate opened to control it from trying to spin the tires. At we also started adjusting the boost set point much higher values instead of just a couple psi because it was making too little of adjustments.

Next run 776rwhp 809tq 15psi
Next was 840rwhp 855tq at 17.7psi
And the final run was 909rwhp 919tq at 20.7 psi

Base fuel pressure 37.5psi
60% injector duty cycle at 7200rpm
21* timing although plugs showed we could've went another 3-4*

Tomorrow were going to do some street tuning to get the drivability dialed in perfect.

In car is one of the lower hp pulls where it was spinning because of the gate settings on the controller.
