video of dons ws6 on the dyno, 550rwhp on 14psi, 12deg, couldnt get anymore boost out of it on the rollers, this always happens and sometimes its worse than other times, oh well that is great power with an unlocked 4l80e and a 9 inch rear to start, the car went mid 10s with only 515rwhp on spray, so this should do pretty good!
