Part throttle pop/stumble through intake

Stumble on a light tip in is usually fuel related. Lean stumble on tip in can be too little or too much AE fuel. Sometimes the decay needs to be adjust also. It doesn’t matter if it did it with your prior chips and still does it with XFI. They all may have room for improvement on the AE fuel. If you’re turbo89 AE fuel doesn’t matter much and if your car is a stumbly pooch driving around it’s acceptable
