Ralmo94, when i order my new prom chip should i send him the bin file for my truck or send him the bin file for a 95 silverado with a 5.7 and 5speed? The computers are the same as far as the 7747 goes so would the newer bin file help out at all in terms of running better/showing for info on my scanner? If not I’ll just stick with my factory BIN which is AZDR
