Wow...I can't believe the tune got you over 100 RWHP. Something else must have been wrong that they fixed while tuning. I'm willing to bet it was spark related. FWIW I put down 300 RWHP on a '94 Z28 w/ LT's and a GM Hotcam kit while running on 7 cylinders (found out when I drove off the dyno and the stick was shaking...burned a wire right before the first run)!
