ok well i have an 01 supercharged LD9. about a week ago i hooked up an aem meth kit to my system and once the battery was reconnected everything went nuts.

im running the GM reflash and prior to this i would have a pretty consistant afr of 14.9 at idle and 11.5 at WOT and 14.9 when cruising. after i reconnected the battery my idle afr is about 13.9, at WOT im about 11.0 and when cruising it is all the way at 10.0. the car bogs down/has no power and it feels like it did when i had no reflash and was driving the car down to the dealer (injectors being too much for the stock system).

i disconnected the meth kit, left the car unhooked from the battery and did the relearn the next day to see if that helped. no luck.

any idea what could be happening/a solution?

thanks
