Hello everyone!
I have been working on cars and building engines for quite sometime, recently swapped out an inline 6 for a rebuilt LQ4 in my Squarebody C10 with a SS2 cam, PAC 1219 springs, upgraded rockers, sheet metal intake, with some BOSCH 0280155931 injectors and a, 4L65e with a stock converter.
I got the truck tuned when it was first installed and drove it around but always felt sluggish, come to find out the rear gears are 3.08. I am swapping out the rear gears to 4.10s with a Posi unit but was told I need to get another tune done.
Given what I am going to get charged for a tune and possibly doing more mods down the line, I want to bite the bullet and get the MPVI3 with the serial cord since I have a wideband gauge already and learn at my own pace.
The question I have is, I understand I have to buy credits to rewrite the gear change but do I have to buy credits moving forward anytime I want to change anything on my tune? Some posts I find state I dont since I own the license for my tune, and other posts state I have to anytime i change and rewrite the tune.
Sorry for the long post, thanks in advance.
