Their claim:


Features:

  • Improves Horsepower, Torque, and Performance
  • With Speedometer Correction for Tire Size and Gear Ratio Changes
  • Dynamic Fuel Management Control
  • Tire Pressure Monitoring System Adjustments
  • Multiple Throttle Sensitivity Levels
  • Made in the USA
  • Designed for All 2019-2021 V8 Silverado 1500 Models

 

It seems like it is a tuner, without actually writing to the ECM?  So I guess they took the Range device, and added more functionality to it?

With the ability to disable Auto Stop & DFM, on top of Throttle Sensitivity adjustment, without writing to the ECM, I'd prefer this over the Range OBD devices. You just get more for your money with the Pulsar LT. The install is fairly simple and you can make adjustments very easily from your cruise control switches on the steering wheel.

 

Here's a vid on the Throttle Sensitivity adjustment.

Yeah, but adding $300 to the price just to adjust the throttle response?  Which is really just a gimick... it adds no power...  

The Range disables start/stop and DFM, and I just click it into Sport Mode when I start the truck...

Mine has been on since friday. TB with the 6.2 and the GM performance package.

 

I changed the tire size from 32" to 33".

Turned off DFM. Still got almost 18mpg on a 300 mile interstate and light city driving trip in the upper 70mph range.

Turned off Auto Stop. 

Set the top speed to 120. (I don't need to go that fast but I don't like falling on my face at 98mph)

Adjusted the throttle sensitivity to one notch above stock. (Didn't think I would need it but it seems to be perfect)

 

Overall I think I like it. Yes it's a tad pricy but for what I was able to do I can live with it.

Cool.  I just saw the claim of "increased power and torque" and thought maybe it adjusted the tune... only to find out that what it really means is "more power and torque for less push of the gas pedal"...  lol

In the end it seems like it's just a range box with a pedal commander built in... I already have a Range, so I can't justify roughly $500 just for the throttle adjustment... I can just push the gas pedal more and get the same response.

The Pulsar seems to be my only option to disable DFM, really wish they were able to come out with the regular Range device for $200. I would buy one yesterday.

I have been checking Range's site regularly to see if there is any update on the 6.2L/10Spd release and just came across the Pulsar LT tonight. For the 6.2L/10spd, it's the only available option at the moment. Yes, it's a bit on the pricey side, however I do like the ability to adjust top speed and tire size (getting bigger ones in May) in addition to permanently turning off Auto Start/Stop and DFM. Ever since replacing the stock exhaust with the Borla S-Type system, the DFM mode sound drives me nuts. It's so much more pronounced whereas stock I could never tell it was even happening. That function alone is almost worth the price for me.

 

I'll likely purchase one soon.

Do you get a rumble when slowing to a stop between 10-15mph? Almost like a backpressure issue? I have the Touring and when coming to a stop I get a rumbling downshift or something that isn't pleasant because in addition to the rumble, it squeaks/squeals a little bit too. When taking it to L9 I don't get that so I'm pretty sure its the DFM. I don't get other odd exhaust sounds when in L9 at any RPM for that matter.

I did a muffler delete and when I slow down, using engine braking, I get crackling and popping...  I get the same on my motorcycles....  I like it.  haha

Not that I've noticed, no. Coasting to a stop downshifts on it's own and sounds good. I do get the popping every once in a while, almost sounds like small backfire, but I think once the DFM is disabled that might go away...least hoping!

Those of you with the Pulsar, did you mount the device to the top of the airbox as instructions state or somewhere else?  It seems to me the better place would be on the vertical support in the cavity behind the headlight.  Also, does the OEM harness plug just kind of hang loosely under the Pulsar one once it replaces the OEM plug on the side of the airbox?

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
