Lexus RC350 Performance Chip

The performance is a little better throttle response. But it has only been installed for a couple of days so I can’t comment on fuel efficiency yet. So I suggest sending this review out to customers at the one month time frame if you want a better review.

This chip actually works. I was a little bit sus and wasn’t sure it would really work. But my power wagon went from 11 mpg to 14 mpg. Normally I would get around 306 miles per tank. Now I’m getting around 400.

This is the 2nd chip Ive purchased...installed this on my 26 durango 5.7. Only other mod is cold air intake. I cant really claim an increase in hp, but my mileage has increased almost 2mpg

You never really know. You know what I'm talking about. There is always that thought in the back of your head. But...it works. Improved throttle response big time. MPG at least by 4. Smooth and rapped acceleration and quiet smooth trans shifting. I'll be damned...it really really works. 2025 Chevy Silverado Z71/RST 5.3.

Easy to install, and my first road trip from Green Bay to Madison I saw a 3.6 mile per gallon improvement. That is an 82.3 per tank gain in fuel efficiency. Incredible!

I was skeptical, but I was pleasantly surprised. I immediately gained 2 MPG and there has been no loss in performance. I have not yet checked to see if I lost -or gained- horse power. I will wait for gas prices to drop before I start checking my HP. So far, I'm happily impressed with Evolv.

I put this chip onto my 2026 ram 1500 laramie. I raised my truck and put bigger wheels on it and in doing so I lost some power and fuel-efficiency. After installation Iimmediately saw results. Two weeks in and some more improvement was made. I got about a 3.5 mpg gain and my throttle response saw a slight increase. Overall very happy with the purchase.

I was kind of skeptical about it but it seems like it works picked up 2-3 MPG and not sure about HP but it had to add about 10-15 HP very easy to hook up just a little time getting to the wires and clamping

speedy delivery ,received it on Monday install was simple enough under the hood!
have drove about 50 miles with it so far and haven't notice any changes with it yet. already had Roush aftermarket high performance program, cold air intake and exhaust system install with an evcX Throttle Controller so she already pushing a lot of hp out.

Didn't have time to disconnect the battery, just wired it in per instructions and took it for a test drive. Significant power improvement plus cured a sloppy 2-3 tranny shift. Seems to be gaining in acceleration performance as mileage adds up. Very pleased with my purchase. Wish I had done it sooner. My vehicle is a 2024 Hyundai Santa Cruz with the non turbo 2.5 four banger. Gas mileage is averaging 29 to 31 mpg even with my heavy foot.

Installed the Evolv chip this past weekend (made sure to follow the instructions by disconnecting the battery (overnight)). Install was straight forward and easy. It's been about 4 days and I've noticed an increase of 4 to 5mpg and that the throttle response is quicker. At this point it seems to be worth the spend.

Installed yesterday
Noticed smoothness in running
Will see after tank or two of gas ⛽️

Great!

Only installed one week ago but so far so good better gas mileage and more power happy so far😎

great product with a easy installation

Good bang for your buck

I placed this on my 2016 Tundra TRD. I havent had it on there very long, but so far my fuel mileage has increased from 13.5 to 15.0. They say it will get better over time so we will see. I drive both city and highway. I started using ethanol fuel and noticed a slight drop in fuel mileage. I recently back to non ethanol fuel and hopefully I will see a slight increase over the gains I have seen so far.

Easy installation & great results

I’ve had it installed for almost a month on my 2025 Ram 6.4 Hemi.Throttle response is a little better but fuel mileage improvements is virtually non existent, might have gained 4/10ths of mpg at best. They say to be patient but not sure it’s going do any better

I was not sure about this product, however I wanted to improve my fuel milage. I ordered the Evolv chip, installation was simple, everything came in the box.

First road trip was 250 miles round trip, I averaged a 1 mile per gallon increase. However there was times I was getting 17 MPG, I drive this route quite often, I have not seen that MPG on that stretch of highway in the last 4 months I have owned this truck.

There is also an increase in power, you can tell on the hills, the truck has plenty of horsepower, but I can tell the difference.

Took a trip to Saskatchewan. Gained 3 mpg on the first 1500 miles.

Very easy to install and I’m getting 3.2 mpg more On 900 miles of driving back roads and highway # 2021 Ford F150 ecoboost 3.5

I installed the Evolv chip module in my 2024 Ram 2500 HD Pickup and after 100 mi I am gaining about 5 mpg in mixed driving city / highway. I am averaging 20 mpg. That means a 33% gain in range on each tank. Wow!

Feel more power 1 mpg better on fuel economy so far

So far the truck is running smoothly, more power and over 1 mpg better fuel. Look forward to see if it gets better but happy with the product.

It seems to work but not had it out on the highway yet
