ID this chip?

[ALXTTA 1]

When I bought my TTA, it came with a Thrasher chip and what I was told was the stock chip. However, when comparing the markings with other examples of TTA chips, it does not match. I'm thinking that it's a stock GN chip, but can someone verify this? Markings are:

(TOP)
DELCO
ACXA
0942

(BOTTOM)
JL2732HS/160002
SINGAPORE 39

I believe that that is a stock pre-recall chip for a GN. The TTA code is available on the gnttype site if you have a chip burner.

Thanks, guys. It must be a GN "pre-recall" chip. I know that the recall was in reference to emissions, but can someone give any more detail? I failed my IM240 test with high HC and now I'm curious if the chip has been the culprit.
