Update - went to Mopars vs the world in Vegas so said the hell with the trans problem,( just soft 1-2 shift ) installed a fti 4000 stall, installed some 4:10 gears with a pair of 28 inch tires, installed the nitrous kit ( 150 ) shot but losing fuel pressure some and ran me best of 10.7 @ 127 et, 1.5 sixty. My other pass was a 11.0 @ 131mph. So im back home again so next week im going too install a stand alone and but it up to 300 shot.Will post my f-up dyno sheet monday. But everything said i had a great time
