I'm looking for the 5.3L Trailblazer ELX or EL tune file for HP tuners-need the whole thing, OS and all. Gotta reprogram the E40 PCM that I've got to run the 5.3L v8. Needs to be the 24x version, what i have here is the 58x...won't work.

If anyone has the requisite file to do a complete OS write for the E40 PCM, hit me up with a PM or post it up here. Thanks!
