Forged Performance: Our First 370Z Custom ECU Flash

Sharif@Forged

A true NO BS gain of 15whp from ECU tuning alone is very respectable. We always choose the highest pre and highest post tune runs. We could pad the numbers we choosing our lowest pre tune, and highest post tune numbers, but we've never done that. Aside from the absolute power gain, you also end up with a engine that is running at it's peak from a safety and power standpoint.

I have seen some cars with bolt on mods, running 14:1 AFR's at WOT without tuning which is definatley not safe. Every car is a little bit different, so the level of gains will depend on the current state of the base tune. For instance, if a 370Z came in with an overly rich tune, or overly lean, the gains could be 20whp+ once we are doing properly calibrating the ECU.

As a general rule, we usually see about 10-15whp from normally aspirated ECU tuning.
