Feels like a whole new car!!!

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

Biggg Year: 2014 Model: GT

  • 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.

Jorgevargas00 Year: 2013 Model: GT

  • Don't do it. I purchased a the Phase 2 kit and Bama and SCT have not been able to get a tune to load correctly, been almost a month so far.

when buying the stage 2 roush supercharger kit does it need the fuel pump voltage regulator kit when you use a stage 2 roush supercharger kit does it come in the kit and do you require it? thx

Dwookiee Year: 2013 Model: GT

  • It does not come with the fuel pump voltage booster. Roush makes a very safe kit. That being said....if you want to make ANY upgrades beyond this kit I recommend buying a "boost-a-pump". Install, solder the two wires for the adjustable knob together. Dont even bother running the wires for the knob up front, just solder together in trunk. The car's computer has direct control over the fuel system and it will take it from there. You will have room for some upgrades after the boost a pump. I started with the same setup.

    Feels like Mad Max!@#$/

    First thanks AM for the good price and thanks to Roush for a great product. The kit is very high quality. The instructions take you by the hand. I installed it myself in a couple weekends. Was it easy? NO. What it hard? NO. It's doable if you have the desire. Then again I'm a mech. As far as performance. I love it... Very drivable at an easy pace. But when you punch it make sure you're pointing in the right direction. Great fun.

    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.
