i have the tweecer rt & GUF1 A9P. I had downloaded the decel setings from the tune exchange & they were working great. I ran into a software issue with BE and was getting an error code 4 message. Clint fixed that and told me that the A9P that I had was corrupt so I deleted my tune and started over. I downloaded the template again but now it wont work. on decel the injectors dont turn off and when i get back on the throttle, my AFR hits 17-18 and stays there for a while. anyone that could help with this please do.

Decel Fuel Shut off for A9P - [tunexchange: Better tunes, less fat]

Basically you need to play with some of the on-off triggers until you get the hysteresis right...
