The basic rule of hp on an stock ally is no more than 90 extra wheel hp to be safe, some guys run much more than that with out issue, other have issues at 90 hp! which this woill put u in the high 300 rwhp range and honestly if you want more than that you need to add a couple more things like a lift pump, and a fuel valve shim kit! but nothing major!!

I have 30 k on my 05 right now, its been modded over 400 rwhp since about 4k, and no real issues yet other than the pos dual mass flywheel!!!
