_______

Hondata's fuel system hardware and FlashPro software mod deliver a real fuel flow increase over stock — 35% from the injectors, 39% combined with the camshaft and pump — for L15B owners whose builds have outgrown the factory fuel system. The camshaft itself doesn't add power directly, but it plays a real role in letting the FlashPro tune for maximum power without losing fuel pressure, and it's what makes running full E85 through a flex fuel kit possible instead of blending.

Tuning stays simple: apply the fuel system mod to your calibration in FlashPro and tune boost, fuel, and ignition as normal. If you don't have tuning experience, we'd recommend working with an authorized Hondata dealer rather than going in blind. Hondata has tested this system supporting builds from a 300hp increase over stock up to well over 500hp total.
