I recently bought a Stage 3 Performance Chip for my 2013 Chevy Impala LTZ 3.6 V6 and I'm super impressed! I never knew that a computer chip could make such a difference. My gas mileage is great and I'd give you 6 Stars if I could. I'm very satisfied and Thank You for manufacturing such a high quality product. God Bless and have a great day.

I bought a stage 3 chip for my 2002 F-150 Super Crew 4x4 Lariat. I noticed a big difference with pretty much everything other than doing a MPG test. I also borrowed a Stage 3 Rocket Chip from a friend who also has a 2001 F-150. I'm not very impressed with Rocket Chip. There was a power difference but it wasn't instant and smooth. On hard acceleration it actually stumbled before it took off. It didn't seem to have near the smooth power with the Rocket Chip. The Thorton chip is way better.

I've had many performance chips in the past. All I can say is WOW. It's the best one I have ever had. My 2023 Tacoma definitely has more power and mpg gains. Worth the money.

This trip really does work I brought the stage 3 put it in my wife's 2013 Camaro with a 6 cylinder you'd swear it was an eight cylinder and I actually got 4 miles per gallon better gas mileage it's awesome chip and takes two seconds to plug in Great price great chip great service fast delivery they actually answer your emails right away it is a great great store to buy from I appreciate it thank you.

I installed the Stage II chip on my 2018 Fusion 1.5 Ecoboost. After about 100 miles I noticed increased horsepower & torque, better throttle response, smoother idle & 2-3 MPG gas mileage gains. Also in Sport mode it sounds more aggressive from the intake & exhaust. Best $60 I've spent so far on my car 5*. Highly recommend Thornton Chip Tuning. Thanks again!
