7.3 MAP fooler

I got my 4.7V diode in the mail the other day from dlonno. Thanks, Dave. I installed it and had a chance to test it out now for a couple of days. I loaded my SuperChips "race" tune back on, which before would defuel when the engine light came on (presumably for overboost). Now when I run high boost (25-26 psi) the engine light still comes on but it doesn't defuel, which is good, but then why would the engine light come on unless it's for something else, like high injection pressure or something? Any ideas?

I would say its your injection pressure too low lik youe said

do you know someone with AE or a snap on scan tool so you can check ICP at WOT?
