I have a 60mm on my car. I run it with a tune and have been able to shift fueling to compensate for it and the other bolt-ons I have.
Effectively it’s no different to adding a throttle controller that opens the throttle earlier than the foot says, on a stock tune it means lots of lean outs as the
ECU gets more air per the tile position (remember drive by wire still has a relationship of pedal movement to throttle body movement) and then has to adjust the trims to suit. My car was showing consistently positive Fuel Trim values and also would lean out when looking at logged data.
I’ve shifted to running about 8% more fuel across the board and it’s better to drive.
Anyway I wouldn’t bother with it, mine was cheap and new and as such doesn’t have some roughness of motion that my stock one had.
