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

This product was amazing did everything as advertised. I turn of dim and on/ stop feature and change the speed limiter and set sensitivity to 3 a boy does it wake up that 5.3 in my 2020 gmc sierra Denali. I truly love this product.

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.

I purchased the Pulsar LT and with a quick plug & play install, simple set up, I no longer have to worry with the DFM or auto start/stop. There are other features on the Pulsar LT that I will use later, but I’m satisfied with the features I’ve utilized!

Great product no more auto stop/dfm, mph is @ 140, throttle response is @15% increase. Very happy with the Pulsar LT. Using it with a 2020 GMC AT4 6.2L 10spd.

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.

I bought this for a couple of reasons, first I wanted to disable the DFM, second I wanted to turn off the Auto stop/start feature, and third I did not like the speed limiter set at 98MPH. Sometimes you need to be able to go over 98MPH when passing a line of semi trucks or slow traffic.As it does not increase HP, I wasn't expecting much of a performance improvement. I was wrong! Changing the throttle response unleashed the hidden power and complemented my upgrades. With a RotoFab cold air intanke, and muffler delete, the Pulsar made it seem like a totally different truck. Performance, acceleration, and sound is crazy. My son in law owns the exact same 6.2 trail boss that I own, I let him drive mine and he could not believe it was the same truck as his. Punching the gas at 60-70 MPH will spin the rear wheels. Never had that happen before.I made a Dodge boy cry when he thought his noisey, smoke emitting, pig of a diesel couldn't come close to passing me. Well worth the investment!!

For the first year it was awesome especially the throttle sensitivity turned up and the speed limiter at 140 but After 1 year of use my my truck started doing odd things remote start started not workingThen i would get random warnings light check engine traction control breaks and then reduced engine power but was very randomLast day of use esc light flashed as i was sitting at a red light and reduced power came on along with every warning light on the dash and truck would not move step on the gas it just idled had to remove the programer in the middle of the road and truck is now back to normal even remote start works again edge was very understanding and did have me send it in for repairs under warrantyjust a heads up that this could happen when it returns it will be going back on the truck even after that happened I would still recommend itUpdate was returned within 1 week they updated it free of charge put it back in the truck and no more issues

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.
