Feels like a whole new car!!!

As expected great increase in HP and it looks absolutely beautiful in the engine bay. With the conservative Roush calibration I dyno'ed at 538 HP / 442 TQ.

Calibration Does this kit come with Roush flash voucher card for calibrating your CPM

  • With your kit will be a box and stamp to overnight your PCM to Roush for calibration, they VERY quickly return overnight. The Roush tune is very safe and conservative. There is alot of power left in tuning which Lund racing can help. Bama does not do S/C.

Installation Do you need to have the phase 1 kit install first before you install the phase 2 or can you just go straight to phase 2 on a stock 5.0 gt

    Love it

    First, if you are going to go this route? Have the folks at Roush do the install. SUPER bunch of guys w/excellent service and the experience to do it right! The power difference is awesome at higher rpms and going from 65-130 is mind blowing. Highly recommend the kit and a Roush install.
