    It’s my wife’s truck but I did build the engine 1 7/8” long tube headers, pop up pistons 12:1+ compression, stage 1 3bolt bumpstick cam, port & polished heads, tsp valve springs, 3” headers back exhaust and the circle D torque converter 3k stall, 30k trans cooler with inline filter, I’ll upload tune when I get home... I did bring it to a dyno tuning shop but the truck is AWD so it wouldn’t fit on the dyno so he road tested. I did some compare files but I don’t see much changed on engine and doesn’t seem to have anything done to trans
