I havn't got it tuned yet. But I did get a dyno tune to break it in. No meth and very little timing I'm at 637rwhp. The meth added over 40rwhp with my last set up. Seat power feels good sofar. The pistons are made for blower motors. I won't be getting the truck tuned till next spring but I...
I bought off the shelf Diamond pistons. I now have Arias pistons custom made to fit each cylinder. I also lowered the compression to 8.6 to 1. I'm running 10 pounds of boost. With the old pistons I was at 9.5 to 1 and 8 pounds of boost.
My pistons were loose when I built my motor. When fresh I hit 703 rwhp. After about 6,000 miles I was down to 600 rwhp. When I pulled the motor I was closer to 500 rwhp. The pistons were toast. I now have custom fit pistons and my break in tune on the dyno was 637 rwhp with no meth.
My shifter came loose. The plastic gasket melted and the bolts came loose. Remove your shifter boot and check your bolts. Congrates on 100k. I have 29k and have rebuilt the motor twice. It's up on blocks now. I hope to drive it before the end of the year.
