The All-New Pulsar V3 for 17-21 Duramax is Here!

The all-new, redesigned, L5P Duramax Pulsar V3 is here and now supports up to the 2021 model year! The V3 Pulsar builds on the already impressive potential of the original Pulsar for L5P and features an entirely redesigned performance strategy. Pulsar V3 now adjusts 4 major components to build power safely: injection pulse width, injection timing, fuel rail pressure, and airflow. We’ve also revamped our shift strategy for improved shifting across the board. The new V3 performance strategy adds 50% more power as compared to the original. The V3 Pulsar: The Best Just Got Better!

The V3 Pulsar is all about bringing together powerful tuning, safety features, ease of installation, and direct control over your driving experience.  The new PN 22402 for 2017-2019 L5P Duramax and the PN 22401 for the 2020-2021 L5P Duramax, are the most advanced performance products in the L5P aftermarket.  The 2017+ L5P diesel trucks are some of the best that GM has ever released and right off the showroom floor, they are impressive. The V3 Pulsar, however, completely changes the driving experience to optimize performance and drivability in every setting. Whether you’re towing or daily driving, the Pulsar provides an instant improvement in performance, and throttle response. The Pulsar also includes adjustment features that allow you to account for any changes you’ve made to your truck. Calibrate your speedometer for tire and gear changes, read and clear diagnostic trouble codes, adjust your TPMS settings on your new wheel/tire setup, or even adjust your speed limiter. After installing the Pulsar, the only thing you’ll wonder is why you didn’t equip your L5P with the Pulsar sooner.

L5P Pulsar Testers Reviews

Best Tuner Out There

This pulsar has been amazing! I’ve been running it on my 2019 L5P since the end of April 2019 after buying it brand new. When I installed the pulsar my truck had like 300 miles on it I now have 14k!!

It’s pretty sick install, plug and play, supper easy to install literally two bolts to take the ECM off and snap the pulsar on and it piggy backs to the ECM that it won’t leave any foot print on the ECM. I take it off every time I take it to the dealer for oil changes and it probably takes 3 min to take it off.

Mileage is way better on the freeway unloaded at the pump it’s about 17-18mpg I run mine on stage 5. the regen isn’t as frequent. Definitely increased power when towing it’s a night and day difference. Also one of the things I love about it is you can change the stages on the fly with the steering wheel cruise control buttons. It’s pretty slick!

Also if you get the Edge insight CTS2 it shows you when the truck goes into regen, a little green light will come on the monitor. As well as these L5P has every EGT probe on the truck already so that way the insight can monitor. It’s pretty sick!


Perfect Upgrade for the L5P

I have been running the Pulsar for more than a month now and overall I very happy happy with everything it has to offer. The install was very simple and could easily be removed to return the truck to stock. Changing power levels is very easy and feel extremely modern. Throttle response & economy have increased both driving daily and towing. I am excited to continue to test all the power levels.


Best Upgrade On This Truck to Date

Had this product for 2 months now with no issues other the lots of smiles and playing with the settings! In economy setting getting best mileage 23.9 and a good average of 21 and in tow setting pulling a 30 enclosed trailer loaded down good average 12.5 mpg and regens cut in half and it doesn’t use half as much def fluid too and the other setting are just fun for sure! Glad to be part of the test run no issues great product as always!


Great Update

I have had the L5P Pulsar unit for over a month. It has great power improvement Mostly drive in the 3rd power setting. Mileage is increased. Adjusted the Speedometer to match my tire size. Overall very happy.


L5P Pulsar Review

I ordered this unit Thursday, 11/14 and received on Monday morning. The install went great and easy – only taking about 20 minutes to complete. The most difficult part of the install was disconnecting the (3) clamp harnesses connected to the ECU. Once installed and cycled through the power levels I could feel an increase in power and throttle response immediately. I noticed one DEF Regen phase while driving nearly 25 miles with the new Pulsar installed but then completed a 200 mile trip with no sign of regen which makes me think the cycle time didn’t decrease causing more regens. I haven’t used any other tuning products so I have no way of comparing, nor do I care to at this point. Cruise control set at 80 for 100 miles averaging 21mpg on Power Level 5 is solid in my book! I would recommend this product to anyone with an L5P.
