Ed it's not creep.....Pat and I think it's because I had around 450lbs more in the car than usually.( I had pat and all his bags in the car, more load on the engine) I'm going to do some Delta Dash logs ASAP and find out whats going on.

Good thoughts.

Did you try the different kinds of gas?

When i was helping a buddy we switched from 76 to chevron to test for pinging and det. The chevron ping'ed less but in the end he switched back to 76 when he got an upgraded map off the internet. No more det. since.
