I agree 100%. In fact, that's probably why so many converter companies give you a free re-stall.... lol
I think we all agree that every car is different, even when they have pretty much the same parts. They can only make an educated guess as to what you need. At least now, they know what they built only flashed 5000 and if it is 5800 that we want, they will know what changes to make to get it much closer.
