. Just a thought.
This is a fact! Thats why you got to have a controller tied to a wideband so it will shut you down when this happens. It has happened to me about 3 or 4 times at about the 1000' mark and thank god for the controller shutting me down, because it happens so fast you can't do anything about it, about 1/100 second i have jumped from 12.5 to 18.5 and climbing due to check engine light popping on( random misfire/overboost code usually) and freaking out the computer. At this point the controller lets the computer take back over and it usually would put me in limp mode and as soon as I got off the track, I could shut it down and start back up and it would be fine as soon as the computer would reset. So I'm not sure you can 100% override the system?!
