buying a 2014 pete 386

[BadDog]

Newbie few questions to add: Just bought a 2011 Cascadia with ISX Cummins 396,000 miles with no history but everything and imap is red. Watched a lot of Rawze videos. THANKS RAWZE!!!! for all the time and effort you put in to help others. (1) I am looking to buy insite but what version do I want to get there is everything from 6,7 to 8.2? (2) If so much is determined by what this sensor or that sensor is saying. Should we first do a egr tuneup/replace sensors or clean all If someone we're planning to do a de-man tune? Or if are these sensors no longer used after a tune?
