I was wondering if anyone has any experience or know if you could swap the computer from a 3rd Gen ram with the 5.9 into a 2nd Gen with the 5.9. Reason I am asking is because hp tuners came out with a software recently that is capable to tune the 03 ram with the 5.9 and I'd like to tune it myself instead of buying a programmer and getting mail order tunes. Or if anyone knows of a tuning software for a 2nd Gen that would be great too
