Well I ordered aldl cable today from red devil river, downloaded tunerpro rt, think i got it all set up, dash and all, I have been reading and reading about tuning for a couple months now, so much so I got myself confused. My question is, once I get connected to my pcm can I make live changes to my stock bin, like egr, a/c and air pump delete, or do I have to make changes to a stock bin then download winflash from tunercat, and reflash my pcm? I like to get rid of the check engine light because my fans are stuck on. Dataloging will be my first step, I understand that tunerpro is good for that, but without winflash I can't do much more? If someone could simplify some of this for me would be great. Think Steveo's robotic tune might be work for me. If i get comfortable with this I will get a emailed tune. Thanks for your time.
