I put the diesel power source s480 add a turbo kit on my 2010 and couldn’t be happier. On stock fuel with a g56 trans this thing will blow the tires off in 4th. Head studs are a must as I’m making about 65psi of boost pressure. This thing rips. Thanks guys

These guys are awesome. They're willing to help you out with anything. You need in fact I bought a Turbo from them and lost their info and couldn't remember their name. They actually called me back to Check-in to see how their parts were going. So I was able to get ahold of them once again. These guys are good stuff.

Diesel Power Source is hands down one of the best companies for high-quality diesel performance parts. Their products are top-notch, especially the Turbonator VGT, the team is knowledgeable, friendly, and always ready to help. Highly recommend for anyone looking to upgrade their diesel truck!

I ordered the 3rd gen Cummins DPS Manifold and have to say I am very impressed with the shipping speed, packaging, and product. I was nervous receiving the box with it appearing that they may have simply put a manifold into a box with minimal packaging... well they did but in a great way. Custom fit hard foam supports cradle it front and back protecting it very well. I received it faster than expected and look forward to installing it. Thank you!

I just wanted to let you guys know how much me and my family appreciate the quality and flawless product you put out on the market. I have a 2005 3rd gen cummins with 264k miles on it. I knew it was in need of some freshening up. We pull our camper thru the mountains of Wyoming and also thru kentucky. I spent a few months on the motor of this truck and purchased one of your 3rd gen stocker compound kits. Paired with a mishimoto intercooler. Replaced head gasket while doing the job. Over this passed weekend we pulled the camper on its maiden voyage pulling the camper about 1400 miles round trip thru the hills of south central kentucky and we never had one single issue, never made a noise, never missed a beat and I wasn't nice to it. She just took it and did what it was supposed to. So thank you for that quality work you do. And I will be back to pick up a stock ball bearing turbo to replace the factory turbo. Awesome work!!

2016 6.7 Cummins 467.7 w/ turbonator and manifold kit. Kit looks to be great quality, instructions were easy to follow. Opted 3rd gen location. It is very tight but does fit. FYI after market air intake may not fit due to 5” inlet on turbo. It does come with a reducing 90 I had Banks and would not fit. Bought a 4-5 reducer boot and works ok. Broke turbo in for a few hundred miles. It’s a beast 50-55lbs boost up top with decent spool up. Egts have gone down slightly. Over all support from DPS has been great and answered any questions pretty quickly. BUILD/ 2016 ram 2500 95k miles. Built trans/converter, Fleese power flow in tank pump, cat fuel filter and separator, Xotic head studs. 50hp injectors, stock cp3 for now, pusher hot and cold side piping, Banks cold air intake.

Turbonator is junk and will explode. And they won't stand behind their product. You don't need a handful of guys as you have blocked everyone who tried to contact you on fb or have left comments. Search yourself on fb, you have been sent videos about the vanes getting stuck and refuse any warranty.

I have been doing business with DPS and I found that the individual on the sales counter has been extremely helpful. Any issues that I have had of my own doing do to truck mechanical issues were gladly and efficiently handled by the sales person (DB). I highly recommend using diesel power source.

I have their turbo, exhaust manifold and their 3g to 2g intercooler boot. The first one split after owning it for almost 10 years, no problem, I’ll order a new one expecting the same and you know, shop local, the boot was more expensive than a competitor and I didn’t even make it 6 months before it doing the same thing. There subpar products have me left on the side of the road with a blown boot. I’ll go through the competition and no longer shop local due to them and their negligence
