k24a2 swapped em1, motor has stock bottom end, k20a type R cams from japan, 50deg VTC gear, type S pump, supertech springs and retainers, rdx injectors, 70mm blox throttle body w/ ported and polished RBC, kpro, 3" exhaust with k tuned budget swap headers, dynojet tuned to 220whp. I was looking to get ~250whp from this build. is the header really cutting the flow that hard? would rather not buy a new one but I will if need be. any ideas as to why the power is lower than expected?
