Installed on 2019 Mustang Bullitt. At first it wasn't really noticeable. Pulled it out for 1st service, reinstalled it afterwards. The second programming was noticeable.

I plugged in the device prior to my last road trip, about 1600 miles. Not only did I get the extra 3mpg, but the added horsepower was enough to help the truck go over hills that in the past several years I would have had to take the truck out of OD. Thyis trip the truck went over the mountains with very little strain on the engine without taking it out of OD. I saved enough on gas this one trip to pay for the devive. Thank You, Thank You, Thank You. I havent noticed that much mpg gain in city driving, but it is still a little better than before. I can still feel the extra hp, which is nice, but not needed as much as on the freeway since I take a lot of road trips. Thank you for this great device, I am more than happy with the results.

great improvement better fuel mileage

I can definitely feel the difference

Well people like they advertise that it is no gimmick, well it's not I got a stage two for my 2014 Silverado and another of the same for my son , he has a beautiful 2011 black SS Camaro that still has under 50.000 miles on it and you can tell the acceleration in both his and mine such a big difference! That is what I like about the chips there is no hesitation anymore and when you are rolling down highway o yea and hit it around other slower traffic big difference. Now as far as gas mileage well I think it is about the same that I was already getting ,but I am very happy with them . I have got two other friends to get them and counting . Alright Smarttune performance chip manufacturer all that I put in this review is true and very happy. I should get a stage three for all the sales I have sent your way lol .

I recently bought a 2019 Mazda CX five signature turbo. I had wondered about chips as mechanics used to do so for a large sum of money. So I bought the stage III thinking what the heck? Came in the mail little plastic box with no instructions… Looked it up online and found my OBD port plugged it in I honestly cannot believe a little plastic box like this can do such a wonders on a already good engine. I Saw results immediately and I would say 30 to 40% more power, low end is absolutely scary it is so different and also made a difference over 60 miles an hour when hitting the accelerator. The new turbo Mazda engine reportedly was 6.20 to 60 time. I have consistently clocked in under 4.00. I don’t know if it is just a match for this engine but the gym looks like having a second engine under the hood. I have been having fun playing around with it and smoking other SUVs. If you have a turbo and it already has good torque in the lower end of this performance chip is absolutely scary. I had a TwinTurbo Porsche and AMC Mercedes and this little old Mazda with the chip will go head to head from 0 to 60. From a start in sports gear it would go quicker than these two cars. All of this to say I wanted to leave a review as I was not expecting this and it’s like a new car… Now has my curiosity and I’m ordering cool air intake and piping and performance exhaust mufflers. Good product guides very good

Love works great

Fast service, excellent product and great results.
