We received our new tuner today, I even bought a new laptop today to use for tuning purposes. I down loaded the latest VCM Suite software no problem, but for some reason our interface won't "unlock". We can't get it to give us a verification code for some reason. I will call them tomorrow, from everything I've heard they have a great support team. I watched a few videos from HP on YouTube today and they are very detailed and thorough. When we placed our order we bought the MPVI2 with the pro upgrade, and several extra credits, they contacted us the next day to verify our shipping and order. The lady on the phone made a commit about how it was unusual for a first time purchaser to buy extra credits...? they actually required us to start an account for the order to go through. So we did and it showed up exactly on time. They were super friendly and professional. I'm wondering if they needed a serial number to add the extra credits to and maybe that's part of the issue. It shows up in our devices tab and even shows our credits and the serial number but no verification code so it won't let use it yet.... and we did try on my 93 Blazer with a 5.3 in it still....
As far as what questions I have, I was putting out some feelers to see if anybody on here has experience with them if I ever have a need for assistance arises.
