im thinking about buying a xzillaraider 2 module for my 03 cummins... its cheaper but is it safe to use? and will it even work on the 03-04 models?

 

i ran one on my 05 and i was really impressed with it. i mounted it on top of the steering column so it was easy to use and easy to read. and there are tons of the free downloads online and they are also easy to swap out. well worth the money

 

quad is out of business would look else where for a programmer
