Plug and play on my challenger
Full disclosure I’ve never run a product like this before. I’ve run power commanders on super bikes and that’s what this product reminds me of so far. Someone mentioned how small it is so I put a picture of it on my challenger tach. I don’t know why you would want it any bigger? The throttle response really improved a lot. Would a $300 unit do it better? I have no idea. This $60 item seems plenty snappy to me. Install time was 10 minutes on my 2009 dodge challenger st8. No error codes came on either. Seems like a lot of fun for the money to me.

Holy crap
I installed this in less than 5 minutes on my Hemi Ram 1500. As far as performance this is the best upgrade I’ve done. No. It doesn’t add horsepower but you will LAUNCH from a stop and while rolling due to the throttle sensor being hijacked by this little device. I did not have to do a “learning” procedure for my truck but the instructions show you how if your application calls for it. One more thing to mention. You can put it into eco mode which decreases throttle response over stock. For someone with a new driver in the home this has been really nice. Put it in eco mode. Hit lock. And toss your teen the keys. For the money I’m extremely impressed.

DANGEROUS
This thing is easy to install, it does a decent job increasing throttle. But.. It deactivated my cruis control, and likes to just disable my throttle randomly. Twice i had to pull over, tun my Truck off and back on to get my gas pedal to work!!! I was going 70 and boom no throttle. That is DANGEROUS

Expected more longevity
Was looking at more expensive models and decided to give this one a try. Improved the throttle response just like the more expensive brands. I wish was changed was a back arrow between modes. Have to scroll through all to get to previous mode. Update 2 months after having this, it threw my check engine light for throttle and lost all throttle control while driving. Had to remove and no warranty.

Works great
People need to understand this isn’t a tuner, it’s for throttle response. But the better throttle response does make it seem like your truck/car is faster cause it’s taking less throttle to increase speed. I put it in my ram 2500 (Hemi) and love it. Night and day difference. Haven’t had any issues or codes come up. Will update if anything changes.

More universal plug
Loved this until the plug broke and now I have everything but the plug and I can’t use it anymore

Amazing!
This is probably one of the better buys. I’ve made this year. It’s an amazing buy. Worked immediately. Can’t say enough good things about this. I had one on another truck that was more expensive. This one did the same thing for a fraction of the price.

Bought this for my brother for his vehicle and bought the 9 drive v1 model for my Elantra unfortunately the v1 came with a different harness so wasn't able to see how it performed against my old Injen Controller. My Brother has been using the V2 in his vehicle for 2 days now and WOW what a difference! His exact words was (" dude this feels like a new vehicle..holy **** lol ") i had driven his vehicle a few times previously myself before the controller install and finally got to drive it yesterday and he was not kidding it's amazing how an item with the same features and does the exact same job as my Injen throttle controller but costs fraction of the price I paid for both my sprint booster and Injen controller can be fun and amazing, hopefully I can find a V2 for my vehicle to play with for awhile but so far only found the V2 for Dodge, Jeep, etc..there are some reviews that mentioned the controller had stopped working after X amount of kms driven or months so hopefully this last longer then that for my brother. Will update my review if anything changes in next little while. *NOTE* Before you can properly use it thwre are two things you need to do. First you must hold the MODE button for a few seconds which will bring you into the settings menu and from there you will be presented with different options with one option called *LEARNING MODE* allowing the controller to learn the vehcilea acceleration position i would suggest making sure you do that first, then second there is another option in settings that allows you to change the controller off time as the day after installing my brother had called me and told me it kept shutting off and thought it was a defective unit until I was able to look at it again and found the *POWER OFF TIME* option in the settings and when selecting it the power off time was defaulted to 180 seconds so we changed from 180 to off and now the screen stays on. Also pressing any one of the 3 buttons when controller turns off will turn it on instantly but suggest setting it to off so your settings don't keep resetting themselves.

I have owned this for one year and it completely changed the way my Jeep performs, a lot snappier throttle response, but right at the 12th month mark the screen started flashing and no longer worked leaving me with no throttle until I unplugged it. otherwise it would have five stars

purchased in july installed in august, was working fine, some time the screen would not turn on with the car ingtion, but it would awake after pressing any button on the unit, and all of a sudden in october when i was at work and about to go home i started the car and the unit displayed ERR COM and i has super unresponsive throttle so to get back home i had to disconnect the throttle controller and just put everything back to stock good thing on a challenger no tools required just a plastic clips to pull the under dash panel off, otherwise i had to tow the car or come back with the tools. its good while it lasts in my case it wasnt that long so for the money you save and replace every 3-4 month this product better get sprintbooster its more money but i had 2 in a different car never had an issue

It's %100 worth the price. I didn't want to spend $300+ on one if this would work the same at a fraction of the price. Also didn't want something else running off bluetooth I had to control with my phone. I wish I had of done this day 1 with my 2021 ram 1500 Warlock. It's a completely different truck now. It was quick before with the hemi but now it's on a whole different level. Absolutely recommend!!
