"Does what it says, I'm getting 4 MPG more, idles better, always had good power, seems to be shifting crisper!"

I've had it in for 2 weeks now and I'm pleased to say that I'm receiving a little over 3 MPG now going from 13.6 MPG to 16.9 MPG. And still seems to be going up a little. Very impressed with this device. I would recommended to anyone.

"I installed this about 4 days ago and we just put 652 miles on it towing a big trailer with a car on it. I was getting 10.1 mpg.. after we got to the hotel I figured out the MPG and it was 12.2 mpg with towing the car trailer up the mountains! Way more power than I thought I was going to have. Very happy so far"

"Does exactly what is claimed it will do... at least so far. Just installed it and man did it wake up the motor! Better response, faster acceleration for sure. Have not checked on any mileage increase yet, although not really that concerned about it. Was very impressed with this product so far. Installed in 5 minutes and absolutely no problems starting up. A big grin came to my face when I first stomped on the accelerator. For 35 hp in 5 minutes I'd say it's a very good buy. "

"Just got this for my 09 F150 5.4L Platinum 4x4 w/off road package, and hooked it up exactly per instructions. It took two short drives for the program to dial in, and it works great. Dynoed it and received 28hp and 4.2mpg gain on the hwy; now getting 22.5mpg at 70mpg which is unheard of with this truck!!"

"This has to be the greatest gadget I've bought for my car. As far as added power I got that right away, turned the tires over pulling out of my driveway, my truck haven't done that since it was new 16 years ago! now for increased gas mileage that's going to wait until my vacation in June but I promise to keep you posted."

"I had doubts about this chip at the price, but my 2014 Ford F-150 increased from 7.8mpg to 10.6mpg when pulling my 24' travel trailer. It also increased to about 18mpg in town driving without the trailer. I just ordered one for my Chevy ranch truck too."

"As I said last month I'll post results. Before installing this chip I was at 12 mpg. And now after running it for a week I am actually at 15.69 mpg. Same gas. Same routes to work. Also I do feel the power. So all in all well worth it. I'm buying one for my old man. It works for me so that's all that matters to me."

"Its great, it give me more horsepower while giving me better gas mileage and torque I would recommend this item to anybody."

I was impressed. My fuel mileage improved and so did my torque. It was easy to install and helped improved all. Instead of getting 16 miles a gallon which I been getting before gone to about 20 to 21 mpg in town. Have not had a chance for highway miles yet but I'm not worried."

"Very good product, love how it added power, fuel economy was up and down but plateaued over time with a solid gain. very nice product and easy to install with instructions."

"I've had the chip installed on my car for a little over a week, so far it seems to be working fine. I've driving normal for that time and no problems. My car runs fine and seems to have more power when I need it, mpg seems to be up too. I have ordered a second one for my ford explorer."

"I love it, it was easy to install, and when it kicked in you felt it. In fact, I like this product so much I told alot of people about it, and talked my father, uncle, and a couple of friends into getting one. And they all seem to love it as well. I'll admit I had low expectations at first, but this product proved me wrong..."

"Followed the instructions from the website crew and hooked it up and went for a drive. Noticed an immediate gain in throttle response and power, but better still was the average MPGs went up by 5.5MPG! Awesome!!"

"I believe the product lived up to what it was designed for, increased power and added MPG"

"This is the best company by far to deal with, they have gone far and above to help me with the problem I was having. i would truly recommend them to anyone looking to make a purchase, i really appreciate what they have done for me.again thank you very much,richard"

"Exceeded expectations for me personally. I drive an 01 ford f150 with 193,000 miles on it and I've gone from averaging just under 260 miles per tank up to just over 340 miles per tank. The truck also runs a little smoother it feels like."

"By far the best purchase I've made for my truck! I've noticed a big power gain and also +3mpg!!"

"Easy to install, i noticed one hell of a difference!!"

"Husband loved this and it actually does work. Better gas mileage and more performance!"

"Installed in an 05 explorer Eddie Bauer with the 4.6, and it got me averaging 19.8 mpg!! Up from 15! over the moon happy!"

"Its been on a week now and the gas mileage went from 15 to 19.9 at 65 mph and an increase in horsepower as well, but why the programmer did not remove the speed limiter?? It still shuts off at 100 mph. I don't drive that fast often but when I want it I need it, all else is better than expected"

"It's been three weeks now and I have noticed an improvement in horsepower, throttle response, and some minor gas mileage. The engine idle is like new, the transmission shifting is so much smoother and quicker merging into traffic and it does have a lot more power. It is meeting my expectations, worth the price if you have few extra coins to spend on your car or truck."

"Product was great was real pleased with throttle response and fuel efficiency in the hwy. Was easy to install, took me less than 10 minutes. I would highly recommend this product."
