Trims in the 5-10% range across the board in a matter of a few minutes... WOT blast had one bank run leaner than 14.7:1 for a short period...

As a temporary fix, cranked fuel pressure up a half turn til he gets the new PCM from Jesse to combat the lean issue.

both rich and lean can do this and if you run it to long like that it can cause you to melt #7 piston also if the ehx don't get out fast enough it will make the cyl temp raise and melt the piston so be careful
