Like spark knock? Almost like a rattle. You'll know it when you hear it

Back down the boost until you can figure out whats causing it, if it's a rod it's too late.

how much power did you put down on the dyno?

I put down almost 470 rwhp i think the sound is coming from the tranny though cause the motor is running good i just heard somewhere sound when i took off on first WOT and shifted to second and was spinning but when i take off rolling at 45 in second the cars runs insanely fast and no weird sound but yeah i cranked down the boos to 9 lbs still runs insanely fast i think it should be putting somewhere around 440 give or tak 10 rwhp cant really noticed the diffrence too much from 12 to 9 lbs.
