Good Day! I just received my MPVI2! I have never gotten this deep before. I am looking forward to going deeper into all of this. I am ok with computers but no GEEK for sure. I own 3 trucks, Two of which can be "tuned". The first is a 72 Blazer 2WD that is in the middle of a LS1 - T56 swap, The second is a 2014 GMC shortbed 2WD 5.3 6L80 and the third is a 1970 SWB 4X4 406CI 700R4 one ton axles Blah Blah! I have been a mechanical wannabe for 35 years and have built many engines and a few automatic trannies as well as several manuals as needed. I will need lots of help! I hope to be a good student and become knowledgeable to the point that I can only make sense to you all! Thank You in advance for all your help!:rant:
