New 408 initial tune... LQ block .030" over, Wiseco -3cc flattops, Callies Compstar rods, Callies Compstar 4" stroke crank, WCCH STG 2 L92's, stock L76 intake, 42# FIC injectors, Holley 90mm TB, Pat G spec'd cam, Powerbond UDP, 85mm GM MAF, 98mm FTP lid, Pacesetter 1 3/4" and ORY, Corsa catback and 6 spd.
Put down 500 RWHP/451 RWTQ with a bad vacuum leak causing a very rich 10:1 AFR. Found #3 and #5 intake ports leaking for some reason. Fixing the problem and retune by Speed Inc on the 29th. Will see what more Jim can get out of it....he said he should be able to get another 15/20+ for both HP/TQ once he can lean it out....

Well, she had her final tune today and according to my shop, it put down 516 RWHP. He didn't know torque offhand, but I'm going to go pick it up tomorrow and see what I think. Graph to post as soon as I get it....
