factory tuning for reliability! No sense in trying to wring out every last hp when the location of the vehicle alone can effect the performance........ Think a car in colorado will perform the same as one in florida for example? Hint: No it wont. Saying a tuner is better than factory is asinine........
Id like to think any tuner can ring out some more HP anyone look at what a tune alone does for a new Cadillac ATS!???? Lol......
Some people in here are just leg humpers...........
