New to the forum, just picked up my first duramax last weekend. A 2016 ccsb ltz with 38k miles, once the warranty is up I plan on deleting. Googled the topic but couldn't seem to find anything. Anyways looking at getting the ezlynk setup and noticed the two most popular tuners are GDP and ppei. Was wondering if any of you guys have ran both of their tunes and what are some of the pros and cons of each tuner. Also what are some of the mpgs you guys are seeing with their tunes. I can already hear some of you guys' saying "why'd you buy a truck if your worried about mpg" but don't really need to hear that. If there aren't really any cons to GDP or ppei and it's really a toss up with who I should go with then mpg could be a deciding factor. Thanks guys!
