NAG1 standalone options

It is true. I am Russell. What you have is an older firmware version from what I sell now and a tcu and a harness not made at PCS. Your trans guy took my work to PCS and tried to go around me and they said no and to go through me. In fact all the other PCS dealers have to go through me for this application. Tuning is done on every car out there. Every customer and car and transmission is a little different and needs to be tuned. To sell the package as a one size fits all does not work. I have probably over a hundred calibration files on my computer from different customers all over the world.
You have to take into account power curves, weight, gearing, everything. It would be like saying here is a tune for and gen3 hemi. Not knowing what cams, head work, exhaust , injectors, etc it had and saying it will work for all.
I take this all very seriously and would rather a customer not buy it than have a bad experience with it. And there are a lot of things potential customers should now that no one but me knows because I developed it.
