Made my car so much faster with stage 1
Today, we are buying our second Chip Tuning device from Thorton as very satisfied customers!
Our first unit was installed on our 2017 Buick Envision (Turbocharged 4cyl) which we drove over 75k secondhand miles. The Thorton Chip Tuning installed in minutes, and was making improvements on the first trip to town. Back and forth across the Rockies, from the Dakotas to the Gulf, never a problem with the engine or tuner. This tuner literally gives you more power and better fuel economy that you can see and feel driving. My wife got tired of me reading the car’s mileage performance out loud from the dashboard monitoring ‘instant and last 50 miles per gallon’. We are Total Fans of the Thorton Chip Tuner!.
Oh – and our 2nd Thorton Tuner will be installed in our new to us 300+hp GMC Acadia. And we Can’t Wait to see and feel these results!!
Thank You Thorton!!
I was impressed with the stage 2 for my 07 Buick, it kept shifting on hills like it lost power. After the installation I drove about 50 to 75 miles and I notice a big difference with power and 1 to 2 mile per gallon. It was so good, I upgraded to a stage 3 for my Buick and a stage 3 for my son’s KIA, hope I am as impressed as the stage 2.
I got big rims on my Cadillac 06 was bout to do an LS swapp came to conclusion I needed more power…..I bought this chip this MFKA got my whip eatn the streets…… Every car I fix I’m putting one in thank you guy at Thornton’s
Very happy with the performance of my buick 2015 Lacrosse stage3 my MPG improved by a least 4-5 miles.
Highway driving is mostly what I use my car for to get back and forth to and from work.
I can say ” I’m a happy camper ”
Two thumbs up to the Thorton chip.
