I guess I'm spoiled over here.....I own the prgrammer that lets me put the parameters I want, rather, the vehicle needs.
Finding a person that will let you program yours or program it for a nominal fee is affordable and easy to find around here.
The drag racing scene is strong so guys with the programmers for 4L60e's and 4L80e's are fairly abundant.
I'd still like to know his build specs as far as clearances go.
Nice to have a baseline to start with.
