new to tuning - question about autocal

[icecoldtexan]

I'm new to EFILive and the autocal tune. I have been using a hypertech hand held tuning device but want to get a professional tune.
I have a 2011 Silverado 5.3L. I am going with Blackbear tuning with the autocal.
I currently have the hypertech tune on my truck, will I be able to download that tune into EFILive and compare it to the stock tune to see what parameters
hypertech uses ?
I will reinstall my factory tune from the hypertech tuner before i use the autocal.
I should be receiving the autocal from blackbear next week.
Also my brother has a police version of a 2011 tahoe, will I be able to look at that tune and compare it to stock ?

Thanks

You could do both of those if you have EFILive. Though I am not sure if you just get an AutoCal from a tuner how you can see maps? Also BB may lock theirs, the Hypertech you will see. The police Tahoe has a lot of timing. I used to 'look' at those when I was a dealer tech.
