If you're so confident with your car throw it on a roller dyno and lets see the numbers off of a dyno spreadsheet.
A graph from an excel document is as worthless as me twirling my fingers in the air. It holds absolutely ZERO value.
Basically with your paragraph summed up. Putting a 8" intake will yield more airflow (with my many many many years in science) making the ECU MUST match it...lol
I'd be interested to see the AFR if these figures are actually correct. I put my money that you're running on the lean side.
