I have a 1991 Chevy c1500, originally a 4.3tbi, however I recently swapped to to a 5.7tbi junkyard engine. So far I have got it running and everything seems to be working okay other than it smelling like it is running really rich. From other post I have read about this swap everyone recommends to replace the PROM chip.
My question is if anyone here knows someone who could either program me a chip, or has one that will fit my truck. The truck has a manual 5 speed transmission and the ecu service number is 16144288. I have looked all over ebay and all the PROM chips seem to be for the 4l60 or 4l80 or they seem to be for a different ecu.
