I wish you could've done a pull with the stock TB and a pull with the 100 MM BBK. Then you'd have a better measure as to what the porting is bringing to the table and what the BBK added. I think the raw airflow of a bigger throttle body added a significant amount. I am more shocked you bolted on the BBK with no issues at all and NO retune required. A few years ago they were very problematic getting synced with the PCM even with a tune. I guess BBK uses different motors in their throttle bodies now? When you put the throttle body on your car before the porting, was the car stock or was it already flex tuned?
Either way very impressive numbers for those mods and still having a car with daily driver capability. Good choices for mod's
