ok at the top of 2nd & 3ard gear while under a load i hear a short bird like sound(a slipping belt) yes i did check no birds in the ebgine bay got the revs 5 grand (no load) and no noise

noticed this right after i hit the rev limtor in 2nd.

Uh oh, you broke it.

Possibly diverter valve?

diverts are new evo's don't they cause a code ??
