I think people are feeling quicker spool up and mistaking it as more horsepower. I bought my lly completely stock and added both the afe mp and exhaust...there is deffinately not a 20-25 rwhp gain. Its a placebo affect, you want to think its making more power now because the box says it will.

whoever said 20-25 rwhp and 40 at the crank, must be doing some good shit!! haha. thanks for the laugh. 5 - 10 rwhp MAXIMUM on a good day.

when i was on the dyno with my stock tune, my truck made 308 hp, with exhaust dp and modded airbox. i know the truck makes 360 stock hp from the factory at the crank, so take that for what its worth.
