Dyno with the 1715 and 2#
This dyno was with a 2# pulley..........not a 4# post title wrong
Mike thanks again ....ok last week I pulled 359/420 with a k&n panel and Mac catback 80 degs and low humidity. I added the 2# pulled and the 1715 micro tuner and TR6's and with a hot pull ...( my truck was on the dyno for along time will he set up the a/f ) I pulled a 386/465 on pump gas 82 degs & 90% humidity. I only pulled once because I was just checking the a/f ratio and it was perfect, 11.7 from 4k to 5.2k. The truck is very strong!! not quite 400/500 but its pretty close with just a 1715 and a 2# pulley

Hi Red92,
Nice, and if you get that truck back on the dyno for a "first cold run" in 70 degree weather, it just might hit that 400 HP mark, or come close.
Each successive pull on the dyno, you'll lose 3 to 8 hp at the rear wheels due to the additional heat in the powertrain. At 80 degrees & 60%-70% humidity, it generally requires a good 90 minute cooldown to pick that power back up, so it sounds like you did very well there overall.
