I hot the programmer from James about two weeks ago. I got 87, 89, and 93 Octane tunes and my total was 400 dollars. While programming my truck, my sct screen started fading out. I called James and he walked me through the rest of the tuning process. He told me that the unit was brand new and he offered to pay for the programmer to be sent to sct but I told him I would cover shipping. James contacted sct, got my rma number and told me to send it in and they Will repair or send a new unit. While I had the programmer, I was satisfied. I was using my 87 tune and I was still happy with the money for horsepower ratio. Throttle response increased, passing power was nice, and no hesitation off the line. When I took the tune off was when I really felt a huge difference. I didn't realize how sluggish my truck is without the programmer. I'm very anxious to get it back.
I want everyone to know that I am very satisfied with The customer service and assistance I received from James. He also supplied my 3 custom tunes for FREE! 140 dollar value! I recommend anyone that wants one buys from James.
The k and n kit was a barely felt difference. BUt the programmer was a big difference!
Hope I helped.
Thanks James!
