go to AWE's site and add up the cost for a full stage 3 with manifolds and DPs. Subtract that total from $13k. With that number in mind, go look at the ASP dyno plot again (noting that "Brand A" is probably AWE's kit). $$/hp & $$/lb-ft gains are pretty reasonable, imo.

You can't possibly compare this to a homebrewed K04 car's cost....not apples to apples.
