evo was tuned by big al at ics,the car was tuned fine,its the last words in your post that killed it.
that little boost knob lol,just 3 psi more wont hurt it will it,car must of been in the 600whp that night.
fully built engine,cams,top end all redone,bottom all done and was even revving to 8600 all day.
he thought because it was a built engine that it could take a little knock and upped it to 2.0 bar while racing a few very fast stage 3 ko4 s4s
see 3 psi was all it took for my boy to do about 10k in damage to his car.
