I have a 04 lm7 engine i am doing a turbo setup on. I do have the matching truck ecm but was wondering if it was the best one to use. If not can i convert to a newer one that has the factory supercharging built into the OS. I would like to write the tune with out scaling if possible with a 2, 2.5, or 3 bar map sensor. Is there any benefit using the 58x setup over the 24x. Let me know thanks.
