Can anyone help with this one? I have 4.7 with a Superchips Programmer. Until recently I couldn't run the full performance setting due to Pinging on our infirior fuel here. Now that I've found a cheap source of octane booster, I've been running the full power setting and very impressive it is! I'd priviously run the performance Towing setting which was an improvement over standard but not as good as the full power setting. The problem I had have is that ocasionaly, it seems to find nutural when doing a kick-down. The gearbox is more responcive in the power setting (the tow setting reduces the kick-down sencitivity) but just occasionaly "slips" for a second or two. In the interest of gearbox life I usualy back off the throttle when this happens, until it catches the next gear. Has anybody else expirienced this? I know its related to the programmer as it doesn't do it as standard or on any other of the three programs available on the programmer. Fortunatly it doesn't do it too often so I can live with it if necessary but would love to get it fixed if possible.

Thanks,

Paul
