For those of you interested, here is what I have found on this vehicle:
It is a 2015 silverado 6.2L with a supercharger added, no other supporting mods, and a body kit that I will keep my opinions to myself on.
Tune in it is a PE raped clusterf**k of a disaster that disables dynamic airflow above 1500rpm, hence no drive-ability and a ton of other issues. Went through the whole tune comparing it to a stock file to figure this out. I am by no meas an expert, but if any of you that know what you are doing looked at the tune I posted, you would probably think the same, if not worse. In short, this is a pig with a bow on it, and I want to get it to where it is fun to wrestle with this pig, rather than wanting to take it out back and slaughter it for the bacon.
I am starting from scratch on this tune, and could use some advice, and I will make a new thread asking the questions I need answered. I have been pouring over the tune, a stock file, reading everything I can get my hands on, watching youtube videos on tuning gen3-5,
I'm proceeding with the understanding that MAF and VVE need to be dialed in first just like the gen3 stuff I have experience with. Main questions I have are about what order to tune what in as there are torque tables, tq management settings, and all kinds of new stuff compared to gen 3.
So, I am thinking I need to set up the virtual torque first with the expected torque to be made with the mod(s), plus a little but not too much extra. Un-rape the PE table, and start with MAF tuning, then move into VVE, then timing, then some minor tweaks to tq mgmt and the DD table as needed.
Any thoughts on this "order of tuning"?
