mhmm. dyno proven on Inspira 1.8M
just curious, this is on WOT right?
any ideas about half throttle, closed loop?
but anyway if my noob understanding of WOT dyno charts are right, if the powerband changes like that, it probably means the air fuel ratio or the ignition timing has changed..
just my guess... [ super big spark takes longer time to generate thus the timing is retarded -or- the spark is super duper big that it burns so fast that the timing is advanced ]
thus kinda curious how most cars ecu will handle this over time
i.e. afraid it may work magnificently well for a short period of time till the ecu relearns and advances / retards certain parameters thus negating any gains
