you can even get a handheld programmer that will tune your pcm to run on e-85 for most gm trucks that are not flex fuel from the factory

If all it is is a ECM reprogram then why do they have 2 different engine options, one with and one without and the E-85 cost more?
Seems to me if it was that simple then it would be standard on ALL engines.
