Like the topic says...

I just installed a 383 into my IROC but its running like crap. The car ran fine before the motor swap but the chip guy seems to think there might be something wrong with the ECM.

Anything out there let me know.

ive got 6 of the things, but where do i look for this # on the ecm or the chip or ???

the 165 will show on the ECM. There should be a sticker on it with a barcode and a bunch of other numbers. I beleive its the last three digits that tell you what series ECM it is.
