I wasn't saying you were wrong at all. You know your stuff

I really think the key is anything governed by the throttle position sensor.

Dang it, I just had a brainstorm to another of your questions in another thread. Speed density systems regulate ignition timing straight from TPS, MAP, and rpm. Less throttle position, more ignition advance, potential for better mileage provided it's not set back by the knock sensor.

Not all MAF use TPS to determine ignition timing. GMs didn't for ages. We have the sensor but I don't know if it's used for that purpose.

 

No CARB# on it. K&N & TRD are the only ones readily available that I have found that are CARB
