    I’ve been trying to find the right Chip and the right Chip that was compatible with a 2002 Chevy Trailblazer LS 4.6 When a friend was talking about getting a Chip for his 2021 Toyota Celica. I told him that I’ve been trying to find a Chip too he told me that Thornton’s has them. Also there prices are crazy inexpensive cause all the roads became one, all the stars were aligned. Thank you everyone I’ll be in touch with my follow up and see what it does!!!

    Just purchased this for my 2021 Colorado. Mostly because I couldn’t stand the lag when the truck shifted gears. Simple install and and immediate noticeable difference. I will buy one of these for any vehicle I own from here on out.

    I just purchased the stage 3 Chevrolet chip. I have a Silverado with a 5.3 v8. Flex fuel. I had power if you stomped it hard. But now it is like a whole another truck. Thanks for a great product. I have one in my trailblazer for a couple of years now. Love it

    Horsepower encrease was amazing. After about two days the Corvette was hard starting, and kept getting worse. I blamed the chip and I contacted Thornton. I was 1 day over the 30 days ,and they gave me a refund. The problem was actually a bad ignition switch.I now I am ordering another chip.

    I have a 2016 Chevy Malibu LT 4 cyl turbo. I have read some of the reviews and decided to give it a go. On my Malibu I did see a steady rate at 40 mpg and climbing on highway with no issue and throughout my regular day to day driving (city) I am seeing and average of 35.5 where on my odometer for a 4000 mile trip I was averaging 28.5 mpg. It appears to be working on my Chevy very well. My 2010 H3A Hummer I went from 12.1 city average to 13.6 average. As far as the horsepower gain I can not say I it was noticeable on the Chevy HOWEVER I am not one to get on the gas just to test things out per say. The Hummer it seems like it may have …. just not for sure. Again reflecting on the ME not one to get on the gas except once to get in merging into traffic and that one moment it did raise my eyebrows. Sorry this is all I have to share in regards to my experience.

    I’ve had a stage 3 Thornton performance chip in my 2011 Jeep Grand Cherokee for at least 3,years now, It is a 4×4 , But the torque is incredible, I had already put a plug and play on it from Summitt, So after adding the chip I expected too much with 22” tires on the Jeep, But overall it gave me more horse power and torque, Before the Pentestar 6 cylinder engine was slow on take off and sluggish, now it’s very quick on the front end. I also got a stage 3 Thornton chip for my new 2001 Chevy Corvette base C5 L1, With my secret button pushed on my Corvette plus the chip it now throws me back in my seat without a doubt. I am more than satisfied. Thanks Thornton’s Performance Chips I am a believer.

    I ordered the Stage 3 for my 2019 Chrysler 300 3.6 L.And it’s absolutely amazing my MPG went up and definitely the Power Went Up.I now use the Stage 3 and I added a Cold Air Intake and HellCat Throttle Body and this 3.6 L flies.I highly recommend this product.Great Customer Service

    Great job

  13. Mario Pasqua

    Got my chip in Corvette yesterday, and what a difference. I felt the difference first time I punched it.Thanks for something that worked.

  14. M. Doxtator

    i purchased a chip for my suburban and fantastic news about the chip, i ran 5 tests to be sure. the first test i went 50 miles on 2 gallons, i did it again and got 55 miles on 2 gallons at 57 mph set with cruise control. i thot this might be a fluke so i did the test again but set the cruise at 65 mph and got 30 miles on 2 gallons, which is 1 mile less than factory ratings. i did the test one more time at 60 mph and went 40 miles that’s amazing!

    i don’t have a computer reading so i went off of the low fuel light and added 2 gallons each time. when the fuel light came on i noted the miles traveled.

    thank you, it’s a keeper.

    Thank u frank reed for a what I hope is a honest review. I like how u worded everything. I to love to squawk the tires and leave rubber on the road. I read one review just a min ago and it totally contradicts yours the person said it took him 100 miles to notice the 60 hp game from a stage three chip does that make sense to you it didn’t to me yours was immediate like I would think it should be I am having a hard time believing in this product because the reviews seem to be mixed and yours is believable where his is not I’ve been around vehicles and race cars my whole life I know everything about upgrades and how they should act that’s why I say your review was believable if this product truly does work like you say it does then I am sold but I need help considering the purchase please send another review telling me more about your experience with this product please from one gearhead to another

    Immediate horse power gain
    Throttle response for a small 4 cylinder engine is incredible.
    Stick shift so 2 and 3 is Very lively and more pleasant and safer to drive
    2nd gear even squawks the tires now. Never did that before. Mileage is also going up getting 43 mpg
    Thanks for a great product.
