So far so good! I used to have issues getting my 2007 Chevy Tahoe to get up in speed I’ve only had this chip a week and I already see a big difference. Will update if anything changes!

So far so good! More hp, torque and acceleration. Can’t tell how much, monitoring gas mileage but it seems better. It was worth the price. Pays for itself in about 3 to 4 months

Within the first week, I noticed the response on throttle had improved. Too soon to tell able the gas mileage, but not going down as fast, for this time of year.

Barely have 200 miles with the chip, but am seeing roughly 2 mpg increase in town. Have not been able to do a hwy. test, but based on current status, I’m expecting at least double that figure. Hard to rate the hp increase, as I haven’t pulled a load yet either. At this point, I am very pleased.

It was a noticeable difference almost immediately. I have a GMC Canyon with the 2.8 Duramax. Picked up about 5mpg around town. Definitely more power and less throttle lag. Haven’t had it in a long trip yet.

Within 2 days fuel mileage improved by 2 mpg and clearly a boost in horsepower. Not sure how much but noticeable. Thanks for this

Only had it in place for approx. 100 miles, but very nice acceleration with added performance. My Tahoe has 170k miles well taken care of and this chip helps the engine perform like new.

I’ve driven from Nashville NC to Winston-Salem North Carolina and back to Nashville and still had over 100 miles left in gas it really works

Ridiculously easy install. Instant idle difference. My work is only 2 minutes away so still haven’t noticed the mileage difference. Noticed will acceleration my rpms rise faster and go higher. Excited for full tank results. Curious what differences there would be for the higher priced items like pedal commander or k&n. But those are alittle more difficult for the different settings. Rocket chip has my full support

Installation was super easy, just plug it in! Within 10 miles of driving with the chip installed, I noticed a big difference in response when accelerating, smooth and more power. After filling up and tracking the gas mileage, I’ve noticed a 2-mpg increase in the city and 4 mpg on the highway at an average of 70 miles per hour. It might be better if we slowed down 🙂
After installing this in our 2019 Jeep Grand Cherokee, we bought one for our Chevy Tahoe and my husband is looking forward to having it in his truck!

We have a 2019 Ford Edge from day one i noticed hesitation after slowing down and then accelerating. I installed the device a directed, very easy. The next day I drove the car to work and initially forgot that I had installed the device until I drove through a roundabout and immediately noticed no hesitation. It worked !!!! Good low cost investment. Thanks

I ordered this chip because I commute 30 minutes each way to work, and was spending way too much on gas. Since installing my it, my MPG has improved so much and I’m filling up less frequently. I’m so glad it worked!

My 2002 Ford Taurus was sluggish on full throttle acceleration. As if the timing wasn’t advanced far enough. As soon as I plugged in the Rocket Chip programmer it would accelerate like I new it could. Love the new found performance.
