I am trying to figure out if the chip I have is a Jeff M. From my understandings, with my K&N filter, and the way my boost guage is acting, I should have hit my fuel cut off. But it just screams right along with no cut off at all.

The chip has a small sticker on top that says ACDELCO AFAU.

I know these pics wont help any, but I thought I would try...

Still doesnt help to find out if it is a Jeff M chip, which one of his chips it is LOL, but maybe this will be a start..

I dont think so, because thats the same chip code i have on my stock chip

Nope, stock chip.

Man, if this thing has this type of boost without his chip, I cant wait to get his chip LOL!!!

Does the sticker that has AUFU on it look like it has ever been peeled off? You may have a chip that was edited...but the past user used UV to erase the chip rather than replace the EPROM with an EEPROM.

Never know. :icon_cool:

How much boost are you seeing? I hope you're not going by the stock gauge... :icon_redface:
