After a full day on the chassis dyno I have the results. We left the boost the same at 21psi to see what the gain is. It went from 717 rwhp @ 6200 rpm to 849rwhp @ 6620 rpm. With NO other changes. The torque fell of a bit from 813 to 777 rwtq. This thing spools like crasy At 21psi of boost we ended up with 31 psi of exhaust pressure. 20psi less than the old turbo. It is a beast! There is way more HP left in it.....1000+RWHP with more boost....no problem.

The down side is we ran out of fuel pump as Turbo-6 mentioned in earlier post. It was a combanation of things that led to this. We run VP Q16 fuel which makes the motor want 5-10% more fuel than standard fuel systems.

The truck is still at the dyno shop. We are over nighting a fuel pump from Jegs to install tommorrow morning. We will finish the dyno session tommorrow.Video link http://www.youtube.com/watch?v=wvtE6z1WRcU
