DiabloSportNEW PULSAR LT ТUNER,COMPATIBLE WITH 2019-2022 СHEVROLET SILVERADO 1500,GМС SIERRA 1500

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.

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.

I love the throttle adjustment with this tuner. I love being able to deactivate the DFM and the auto stop.

I installed this on a 2019 Silverado 1500 LTZ with 6.2 l. Engine. My truck has a six inch lift on 35x12.5 R20 and is still getting nineteen miles to the gallon on the highway. I turned off the DFM, auto start/stop, and increased throttle body responsiveness by 20%. I also adjusted my speedometer to my tire size. Fantastic product and I like that I can make adjustments on the fly when necessary.

No customer service. All phone numbers not working. Product did not work and cheaply built.Could not get past first settingWhat a fraud! Stay away!
