Was reluctant to buy, wondering what gains I'd receive. Glad I did. Improvement in performance was immediate. Accelerates faster with more power at the wheels. Feels like a different truck. Install was pretty straightforward although it took longer than stated in the instructions. The harness is bulky and presents a challenge to stuff neatly behind glove box. Overall very satisfied.
I'm saving so much gas and way more power
I had installed my headers and intake about a year ago and went from 17-15 mpg to 15-13 mpg but had good power. Now power is amazing pulls hard, only thing is the price I feel like Unichip should have dropped the price on these but auto anything was the best deal and fast shipping and great costumer service, they emailed me right back with any shipping problems.
