    • This thing is well worth the money!!!!
This thing makes your truck turn into a beast. No more annoying auto start/stop, no more DFM, and I put the speed limiter to 130 just because I can (goes up to 140). These were my primary reasons for ordering this thing. The throttle response feature is just crazy. I started on the lowest and worked up to 5 just to see the difference in performance. It now has crazy acceleration and no more lagginess like before. I left it at 3 as that’s plenty for everyday driving, but you can go to 5 if you want a rocket ship. That feature is adjustable on the fly. It is a bit spendy, but damn it’s worth every penny. This is how the 6.2 should have been from the factory! Installation was a breeze. I don’t like where they have you mount the unit but there really isn’t another place to put it that I could see. Again this thing is the awesome and I would highly recommend to anyone. ... show more

    • 2019 Chevy Silverado 1500 5.3
Great product. Easy to install and works as described. AFM/DOD turned off, auto start/stop disabled and on the fly peddle adjustments. Can’t ask for much more. Has additional features that I haven’t needed yet. Truck flat out flies with the throttle turned all the way up. Amazing to see how much they keep them turned down from the factory. ... show more

    • Works Exactly as Advertised – Truck Runs Wide Open
Installed this Pulsar LT on my Silverado and it works exactly as expected. Install was straightforward and it immediately made a noticeable difference in throttle response and drivability. Truck runs wide open without hesitation, shifting feels better, and overall performance is improved. No warning lights, no issues so far, and everything functions like it should. If you’re looking for a plug-and-play option that actually does what it claims, this one delivers. Would definitely recommend. ... show more

    • Much better than the OBD ones - Delivers What It Says It Can - Programmable!
Using this for weeks now in a 2020 Sierra 1500 with the 6.2 and 10 speed. Installs easily, although the written instructions need improvement. I would recommend watching the installation video. They do provide a QR code that'll take you to their videos. The features are all programmable through the buttons on the steering wheel. The throttle sensitivity is easily adjustable even while driving. Very cool and useful. When disabling the auto stop feature, the light on the auto stop button turns off as well, unlike with the units that plug into the OBD port. With those, the light is always on (even though the feature is disabled). Just nicer that way. I have not had to modify ratios and all, but it is a nice feature if/when needed. One thing I really would like to see added, preferably with just a firmware update, would be the ability to have the truck go into "sport" mode every time the truck is started. Other than that, this product has been great. Between disabling AFM and also increasing throttle response, this will make for an entirely different driving experience. By a lot. You'll feel the difference in the seat of your pants kinda thing. So definitely worth it just for that. Well worth the price increase over the other types IMO. ... show more

    • Waste of money
This was a phenomenal waste of money, constantly putting the truck into limp mode and throwing codes. No it's not the truck, as soon as the tuner was unhooked the codes were gone and truck working fine.

    • Good features and build quality, but pricey
I bought this mainly to turn off the Dynamic Fuel Management on my 5.3 Trail Boss (IYKYK), but also because of all the other features available to help dial in my truck to my preferences. Besides turning off the DFM, you can also turn off the Auto Start/Stop for the engine, adjust throttle sensitivity, adjust the speed limiter, correct for different size tires. This is a plug in module that is easy to install. I think the average DIYer could install it and set the programming in about an hour. It includes a T-Harness that gets plugged in between the engine module and the factory wiring harness. The harness is of great quality, and even uses the same type of locking cams to secure the plugs. I can definitely feel the better throttle response, and it's nice not having to manually turn off the Auto Start/Stop every time I start the engine. The company falls under the Holley (Carburetor) company, which is reassuring to those motor heads out there. So why 4/5 stars? 1. It's a little pricey. Don't get me wrong, I appreciate the quality and features, but it seems to be at the higher price range for these things. It can be subject to software updates from the company, but to do this, you would need to purchase a special cable to connect it to your computer, which is more money. 2. Setting your desired features is a little quirky. In the programming mode, it utilizes the speedometer dial to indicate what setting the feature is set at. With touch screens in practically every vehicle, it would seem to be a more natural user interface for setup. The good thing is the company has videos on how to set it up, and others on YouTube have similar videos. Overall, not too bad. I would buy again. ... show more

    • Great add for 2019-2020 chevy silverado's
Initially bought this to shut off Chevy's stupid auto start/stop feature. Useful too though if you have two sets of tires and rims for quick adjustment of tire size relating to MPG tracking. Have also grown fond of the settings for adjusting the throttle response. I have it set at about 20% over factory and absolutely love the responsiveness of my truck now. No effect on mpg unless you are getting into the throttle which you have even without the programmer. Very happy with this upgrade! Installed on 2020 Chevy Silverado Trail Boss with 5.3. ... show more
