So definitely not seeing the same gains as the original post, or anywhere near, bumping an old thread for input. Baseline dyno pull was done stock map and just BMC dropin filters, at 419/444. Added chargepipes and catless downpipes, bm3 stage 2 map and dyno at 436/504. Significant torque gains but not as much of a HP gain as I expected. Any thoughts on if these numbers seem right, or if I should be looking at something else?
