I just replaced my cam with a summit racing cam 209 intake/217 exhaust with a 550 lift in my 2015 Silverado with the 6.0L. I also did the VVT delete and was wondering where to start with tuning. I just purchased the MPVI2 and raised up my idle to help smooth the idle but looking to unleash some more power and torque I am very green and trying to learn as much as possible
Post your tune file here, want to take a peak at it.

I think this is it
I'm a green tuner, but a 34 year diesel mechanic....
First learn how to set up your scanner to log the proper parameters...
Then learn to log graphs
Then learn how to dial a MAF Tune (I did my first with o2 sensors, so closed loop, no Power Enrichment)
Then learn how to dial MAF in in Open Loop using a wideband.
Once you have that you will be ready to dial VVE (I played with VVE closed loop MAF fail, no harm in that, but wideband is best)
It is alot to take in... Its all about learning how all the tables and modifiers work togather. And the better technology gets, the more complicated it gets...
Run 89 octane fuel in that truck and get power enrichment to kick in way sooner. It's basically disabled on those heavy duty trucks for emissions, towing, fuel economy reasons.
