Holy crap!! I strapped the car down again today and made a few minor adjustments to the tune and put down 494rwhp and 460rwtq! The first few pulls the car was putting down the same numbers as before. I was just about to call it quits but decided to add 2* timing. We made one pass and it put down 482. That was the highest all night, so we made another pass. 4 passes in a row, all with out even shutting the car down, picked up 4-5 hp each pass until I got to 494. The first pass the ECT was around 170, the last pass around 190. I guess my car feels most comfortable around 190! I'll scan a graph tomorrow. Again, this is through 5.3 heads, stock LS6 intake, and 93 pump gas! Full belt etc...

Very nice!! I hope to get to the magic 500HP number soon. I'm running less compression 11.1:1 also my cam has less duration but more lift @ 631 on a 114CL. I'm also running 59cc ported LS6 heads. Good luck in getting to 500HP!!

Very nice I am impressed. I have a 395 and only made 489 and 472 tq. My tq was better but I have the Fast set-up. I am working on retuning the car and as I see what you have made I have hope.
