Hey DT how much boost was you getting out of that 62? Did you dyno it?
I ran 6lbs and put down 370hp/400tq through a 4l80e and 20inch wheels. I now have a 9lb spring but haven't been back to the dyno. I'm thinking it should be around 430-440 rwhp. My current 1/4 mile time is a 12.7 with a 1.8 60ft. I think the truck would run better in the quarter if I could get my 60ft a little lower.
Edit: Also included are the 6lb and 9lb wastegate springs
