Diagnosis machine
 

Hello,


I am new to this fórum and this is my first post.
The thing is that I own a 2001 deville limusine. I have completely rebuilt the engine, of course changing the cylinder head bolts by the studs that Northstar performance sells.
If I can be of any asistance to anyboy on the engine rebuilt do not hesitate to ask.


The real question I have is about the diagnosis machine, does anybody know which one is the most complete at an affordable Price? I Heard about one called GM Tech 2, is this the most complete one?


Thanks for the help.
