I am new here, but want to see what else I can get out of my little truck. 2003 s/c s/b Sierra LQ4 .030 over Lingenfelter GT7 cam, comp valvetrain, 4L80E with Radix and 2.8 pulley. I just made 472hp and 495tq at the wheels after some tuning on 91 octane. I need to add long tubes and a bigger throttle body. Any ideas on brands/sources for these.
