    Just purchased tuner kit and stage 3 tuner chip for my Maserati ghibli SQ 4 2014. Looking forward to the plug n play applications. Thank you. Sincerely Gregory S Napier

    Purchased stage 3 for my 2007 Ford Sport Track with 4.6 V8. No idea where people have any trouble with this company. I placed my order and received the product within just a few day. I recently finished the first 150 miles and although I doubt some of the HP projections I can say my purchase was worth every penny of the price given the nice increase in performance . Not paid much attention to milage as Im having too much fun with a V8 that now feels like one.

    Purchased a stage 2 for my 2009 Pontiac Solstice 2.4L 4 cylinder. Noticed a difference right away! Just ordered a stage 3 for my 2015 GMC Sierra because I tow a cargo trailer and sometimes a travel trailer. Can’t wait to see what it does for those situations. I will let you know.

    Was truly doubtful of it working but bought the stage 3 and to my amazement my Hyundai Sonata v6 became a monster on the street and I couldn’t be happier thankyou Thornton

  6. JT

    Purchased stage 3 for my 2010 Lincoln MKZ. I drive on average of 3500 miles per month as a OSS rep for NAPA. After installing the chip there was a definite improvement on throttle response and idle characteristics. My average MPG has definitely improved as advertised as well. Definitely well money spent.

    I was skeptical at first,. I purchased stage 2 just see if I tell a change in performance, I have an 08 Altima 2.5s, full cat delete, cold air intake, resonator swap to a 36″ glass pack, straight pipe to duals in the rear, performance coils.
    Well I put it to you this way guys and gals, car comes stock 175 horses, with stage 2 Thorton chip alone with upgrades my 08 Altima running like a scalded dog,. Is close to 300 hp, I’m itching for the stage 3, I know I’ll be there 300 hp. Chips are unbelievable as far as performance, great job Thorton.. thank you

    This stage 3 chip for my 2012 Ford fusion v6 is absolutely amazing? Did exactly what they said. Had the chip in 3.days. plugged 🔌 it in and the power and speed difference was truly awsome!awesome!! Would highly recommend this product to anyone. Good job thorton!

    I purchased a Stage 3 chip for my Hyundai Sante Fe and my Mother’s Subaru Forester as well as one of the Bluetooth diagnostics chip. I was pretty sure my mother was going to stay with her original opinion in saying it was a waste of money but to my surprise and delight she loves it. She no longer has lag or poor throttle response plus she said that has seen a 5mpg gain in gas mileage. I have not seen any change in my Gas Mileage sadly but it did stop my biggest annoyance with my car which was the throttle response and lack of power i was previously having. My little old Sante Fe has got some great pep and responsiveness now so overall I am very satisfied with the purchase and would strongly recommend anyone even slightly interested in trying one out in their vehicle to definitely go for it. You will enjoy your ride so much more.

    I have a 2020 land rover defender with a 2.0 4 banger turbo. 296hp rated. Seem to had a turbo laps so I bought the best one first. Noticed instantly the lag was gone, the pep in the car was stronger and the mage while the car weighs t400lbs jumped about .8 mpg. Didn’t expect miracles but I am very happy with this purchase.

    I bought a 2021 Toyota 4Runner TRD pro based on Toyota’s reputation for reliability and performance . Unfortunately when put in real life situations it was a dog sled . I was completely disappointed with the performance of the 4.0L V6 motor . I ordered the stage 3 performance chip with a lot of doubts . I noticed better performance off the line and a little more power. But as time went on this plug-in chip has made the dog sled drive more like a Porsche . I noticed the other day as I was pushing redline up the winding canyon hwy74 that the motor reminded me of Toyota’s racing motors lots of power all the way through the rpms especially around 4K-5.5k I really could not believe it was the same car . Many people have asked me what kind of motor I have in my 4Runner . They are amazed when I tell them it’s just a plug in chip . Thornton chip tuning chips are worth every dime ! your performance will gradually get better and better and better !


    2009 Maxima. Works as it says! Just bought one for my silverado! Be back to comment on that one after my assessment.

  14. Gerald Hon

    I’m very impressed with the stage 3 chip I have a 2022 trail boss with only the 2.7 turbo 4cyl and it didn’t take even 5 miles if that to tell a big difference in horsepower, Torque and acceleration it’s pretty incredible the difference that it made I would recommend it highly to anyone that has a 2.7 L turbo

  15. William Strange

    This tuner really works

  16. George Griffith

    The level 3 chip I bought from Thornton chip tuning for my ’96 mustang gt has done far better even than I expected it to do. When I put the spurs to my pony it takes off like a beast! I’ve been using it for over a year and the mpg has been far better even than advertised too. Have gotten 8 mpg better fuel mileage!! I highly recommend the level 3 Thornton chip for anyone with a mustang gt, it delivers what’s promised!!

    • Theo (store manager)

      Thank you George! Please feel free to reach out if you have any questions. Looking forward to your next purchase!

  17. Joe seph

    I can say for sure as this relates to my 2005 TrailBlazer they’ve made this straight six run like a V8 with a bad attitude.
    Bottom line these guys know what they’re doing, very impressive.

    You can definitely feel your car take on another personality . The only issue I had was I started with lowest chip snd ended up buying the highest chip a month later after wagging more and more with my STi worth every penny if you don’t wanna mod your car beyond a plug-in chip thst can easily be deleted from vehicle when you need to! Definitely recommend!

  22. Craig
