I put this tuner in my '09 Frontier and it really has made a difference. Once I installed the updates and figured out how to tune it, I ran the 91 perf tune and the gains are impressive. Like most others, I have actually gotten better gas mileage from the 91 perf rather than the xs fuel saver tune. Great product!
