What does defueling mean?

I have been reading posts with the term defueling between shifts when chips are installed. What exactly does this mean? Thanks.....

Re: What does defueling mean?

Just what it says, the fuel is cut back during the shift, which cuts power a bit so as not to overstress the tranny. Usually you won't even feel it under these circumstances. Another occasion for defueling would be if the exhaust temps(EGT) go too high, causing it to defuel. Then you would feel the power flattening out somewhat. Hope this helps!

FASTFRANK,

GWA is correct and it also will pull back fuel when you exceed pre set EGT on the Attiude Monitor, if you get the Edge product, to reduce fueling when you exceed to max EGT level you asked it to watch for. In other words you get the Edge and Attitude, you pre set that you want the max EGT to be 1300 degrees, if the Attitude sees that or more as you climb Mt. Everest it will slowly pull back fuel and set off an audible alarm to reduce the fuel to reduce the EGT level you pre set. Basically it's EGT proof, we sell a lot of them because folks just want to set it and forget it! Call me if you have any questions etc.
