My 2002 SS Camaro with Whistler Built 427 LS7, PRC heads, forged bottom end, stock intake. made 560+rwhp this pull, ended up at 570, bad 02 Sensor and MAF sensor made Cal Hartline's tuning day difficult. Once the parts were replaced and the new tune it runs like a dream, no dyno since the re-tune. Might be making around 600rwhp now.
