I could use some help getting the fuel gauge in my Colorado back to working correctly. I just finished up swapping a 5.3 into my ZQ8, and now the gas gauge does not read correctly and it runs backwards. Gauge empty = full tank / Gauge full = about 1/2 tank. I wanted to see if anyone has a stock tune for a 2004 - 2005 Colorado / Canyon that includes the fuel gauge tab. Every tune I pulled form the HPT repository does not have the fuel gauge tab on it. Any help would be greatly appreciated
