It also has to do with the third injection event on the 04.5 and newer trucks. Mine does it also, many searches on the net.

So where can I see the breakdown, is plain english, for what each tune actually does for the truck?

So by looking at the tunes, I cant tell what is what. I dont have a puck, which tunes should I look at?

The 7130 has the ability to talk to the ABS module enough to make my "ABS" and "BRAKE" light stay on for 10 miles after every tune change.

Got it taken care of. After I dumped everything and reloaded it, all is well. Thanks.

I tried that and now when I have to power down the diablo and power it back up, the program seizes up on my computer. Im going to dump all of it and try again and see what happens.

Ran the latest update on my U7130 and it says "Application missing or corrupt". Now my computer cant auto find the tuner and none of the manual settings work. I followed the help instructions but no dice. What do I do?
