Koomaha【Pre-Calibrated, Direct Fit】Replacement for 6.7 Cummins Turbo Actuator HE300VG Part# 5494878RX 5601240NX 68481772AA

Previously I was living in my camper when this went out and I had to pay a dealer $4000 to replace and it failed 3 years later outside of warranty. That was a genuine MOPAR actuator part that still failed in 3 years after spending all that money. I decided to replace it myself this time and so far it has worked flawlessly. If this lasts anywhere near the previous part then I will be very pleased with this purchase. I had a couple questions for the seller and they were very responsive and I wanted to leave this review to support them. I have a 2014 2500 Cummins 6.7. Required NO calibration and it works great. YouTube has some good videos on a couple steps to ensure you replace it correctly. Fairly simple to install.

Update 07/21/23 Amazon great job on $95 restocking fee if outside 30 day window while product have 2 year warranty. Long story short get yourself a HOLSET unit not this piece. Seller is nowhere to be found. Amazon issued a refund with $95 less due to restocking fee I wonder who will get this actuator you will not be happy. On hold for over 1 hours trying to get a way to reach out the seller. Update 07/18/23 So update will just give 2 stars, code remained permanently and got me straight Holset brand 1 week ago. So a bit about my unit, so i am having boost and will just cancel and jerk the truck or lets say i have 10psi will drop to 5 and jerk it and i will have the pedal to the metal. On exhaust brake you can feel it struggles to run. It didn't last 2 months. Update 6/18/23 Its been 2 weeks since instalation and turbo lag is too big. You might get code P226C but i learned how to deal with it but giving the circumstances this product might go back to the seller. I do a lot of towing and this is no good for me. Looking for alternative but if you are not towing boost is there and no lag only while towing. Will do another update to give proper review. I just installed it today on my 2018 Ram 3500 6.7 Dually 6/4/23 and honestly boost i had compared with what i got is wow. Before was barely 1psi now 20-22 psi at 1st and second gear. I would recommend this product at this time. Will update in the future due to 2 year warranty how this product works. Only down side is coolant drain and mess but at the end i got my truck full power back. Fallow instructions in the video and wont make a mistake hit red to clear white to start programing and install actuator and blue to finish programing. Hope video of my OBD port helps to see the boost and helps next guys buying these product.

Buy this part and save yourself a lot of money because, it worked as advertised, comes with the calibrator and is a quality part.

Pre-calibrated ? Not sure if it’s a fact . But it’s working fine and I will amend this review after I confirm the calibration.

Part didn't even last a full year and stopped working... they claim to honor their 24 month warranty but after multiple attempts to get a replacement or refund, I can't get a response all of a sudden... dont waste your money!

So far so good. It took me about 4 hours to install by following a video on YouTube. The most difficult was getting to my coolant drain plug. Everything else was rather seemless. The key is having all the right tools.

Fit as it should. Works as it should. Very easy to install and program. Hardest part was getting the old one off. Make sure you have a grinder and bolt extractor set for 10mm before starting.

Actuater only worked for two weeks then seized up don’t waste your money just buy OEM! Now I’m out 1200$ in labor fees and they won’t let me return this one.
