    need stock 4.3L file

    The file repository is blank on a stock file for a 4.3L Silverado 2001-2002. If anyone has one I would really appreciate it. Thanks

    Try a S10 same year. Just remember (IDK if it matters) GM swapped from poppets to mini-injectors in 2002 IIRC. Also know if you have EGR and/or AIR....compare to the S10 year if it had it or not. I dont see why the S10 file would not work in terms of the settings. Same engine

    Sorry to bring up an old thread but I need a stock tuner for a 2002 to 2005 S10 if anyone has one.

    Be more specific. An 02 is going to use a 0411 red/blue PCM and be a 512K file and a 03-05 is going to use a blue/green PCM and be a 1MB file.

    Sorry I did not know that but I'm mainly looking for the injector setup so I can compare between my 2001 with the older style injectors and the newer style (2002 to 2005). I upgraded mine and want to compare the two setups. I would think the injector setup should depend on the injector and not the system it is connected to but I'm no expert. I'll take what I can get because it seems no one has a stock tune.
