They’ve done all the testing they have all the numbers. This thing is legit. I put one on my 2020 Tundra then I put one on my bosses 2021 Tundra and he loves it!! Anyone else I know I highly recommend worth every penny.

This has woken my truck up it’s a night and day difference would recommend it to anyone

Made my 2015 q50 sound so much more aggressive on the throttle open and quiet while I'm cruising. Completely satisfied with the look of them and that they don't give any codes.

Although very difficult without measuring precisely how much oversteer has been mitigated since I installed it, I can say that cornering at aggressive speeds has changed. Changed for the better for a driver who understands inbound/outbound power thresholds/grip and has the skill. Otherwise this is simply a nice looking addition for whoever is changing your oil to admire.

I am happy with the purchase, but guessing the majority of buyers should simply take a picture after installing and brag about the looks.

If purchasing, make sure this is for you and not just YouTube.

Bought the tru controller for my 24 Tacoma sr5 can definitely feel the difference in response when put on sport mode on the app. Install was easy just have to connect 3 sensors. I recommend this to anyone considering buying I was hesitant since there is no reviews but they do offer 14 day return guarantee

Fits perfect and came quickly

Awesome product fits and looks amazing

One hour install but instant pep in the wheels. Turbos sound good regained the pep I lost with 3 inch lift and heavy wheels and tires.

Thank you it fixed perfectly I would love to see you develop more body style for the 2015 Nissan Altima

Ordering, customer service when ordering, shipping super quick, customer service before install, all 5 stars. Great people to work with. And if your looking for a little low growl at idle and coast, a nice louder growl under power, great balance for comfort but still get some sound and performance.

I love it so much just like they should have come our factory like that and would highly recommend to anyone who are also car enthusiasts!

Coming from a 2023 3.0 Premium Supra, my Hyundai Santa Cruz needed some serious response time improvement as well as some off the line Pep. Stillen helped with both. The Santa Cruz will never keep up with a Supra, but its at least tolerable thanks to a Stillen upgrade. Roll-on for passing is 100% better as is Towing with the added torque. Well worth the upgrade.

I had an issue with my truck getting warmer than I liked while sitting in traffic, this solved my problem

My wife was pleasantly surprised at acceleration! Lots more torque in normal driving situations. Great improvement for the money. I saw the prototype tests and glad it came to production. Awesome

Install was eazy to about 1 hour just loosened the two clips next to the headlights and the bolts that hold the of grille to the support pulled the grille back a little bit to remove and install the air diverters. You can really hear the turbos spool up and fell a difference in throttle response. Painted them to match the true controller
