i purchased the p1sc kit for my 06 gt, i installed it on the vehicle with 8,000 miles, at 22,000 miles it started making a rattling noise and a humming noise, procharger says bearings and it could be between $700-$1500 to fix, also it has leaked oil from the drain plug since i changed the break in oil, i have purchased drain plugs and o-rings from procharger and it still leaks...........i am completely disappointed with this system.....also before it failed internally it would only pull about 7-8 psi of boost with a 12 psi pulley.....what is going on here.....then the last guy that dyno tuned it said i had blown head gaskets and only tuned the car to 6,000 rpm nd it still made 425hp and 400torque......i cant keep dumping money into this thing every week...........although it did go 12.20 @ 115 on 17" bfg drag radials...........any ideas??????
