ok so i have the predator set on extreme rkl, i put in a boost fooler, made a 4'' intake horn,5 inch turbo back exhaust and intake, and my tranny has a triple disk and valve body my avg boost at WOT is around 43-46 and without a load my exhaust temp does not touch 1350. i feel good progressive low end power with the predator but i recomend a boost fooler with it to keep the temps down. i also did finally get my fass 150 put on but it didnt seem to make feelable difference. without the fass i dynod 453.11 and 910.88ftlbs... O and my predator for some reason doesnt find or fix engine codes so i had to go get a kragen special obd2 tester which works great.
