Edge (like many other plain tuners) just has Generic tunes. If doing anything later on it will not be able to accomodate your needs...
Like for example,
For the last year I had Standard custom tunes for my SCT...
I upgraded my injectors and studded my truck last weekend. emailed Vivian and she sent me a revised tune to REFLECT my studded truck and larger injectors making more power/ better economy... A generic tuner (like edge, banks, ect) would NOT be able to do that!
Do it once, do it right, get more and safer power by getting a SCT tuner. It will be better on your HG also:nod:
