4.8/5 Stars out of 14 Reviews
These injectors are awesome. My truck puffs smoke upon every gear shift. I have a Cummins 24 valve Dodge that never smoked from the time that I bought it. The power that is produced is unbelievable. The truck is also getting around 2 miles per gallon better gas mileage. While accelerating under a load it blows black smoke, but dissipates while at highway speed. Towing is effortlessly. Worth every penny.
Huge power increase
I got them quicker then I expected. And I haven’t been disappointed so far my truck has a lot more throttle response and a lot more power.
125hp injectors
Love the injectors will definitely be doing business with you guys again wish my stuff would have came with some stickers to rep you guys also lol

Questions and Answers

For 150hp injectors do i really need a twin turbo set up? or can i just put a big charger on it?
View Staff Answer 
We recommend running a compound set up on the truck. Compound kits offer you a better fuel/air ratio for daily driving characteristics. Larger single turbo’s often have more turbo lag.
What turbo upgrade is recommended? I have 98 24 valve and looking at 100hp injectors, big connector tubes, stock vp 44 and airdog lift pump. Why do I need the upgraded turbo? I am not going to race the truck but planning to build it a little as a daily driver and show truck.
View Staff Answer 

Too much fuel and not enough airflow is the reason a larger charger would be needed. Incorrect air/fuel ratio…excessive fuel to air ratio will result an incomplete combustion of fuel and excessive black smoke. Give our diesel experts a call at 1-888-343-7354 and we’ll suggest the best turbo for your application/needs.

Dose these ddp 75 hp injectors come with new rings and washers?
View Staff Answer 
Included with these injectors are new injector O-Rings as well as new copper washers.
Do I need a bigger turbo if I'm only putting a 75hp injector?
View Staff Answer 

The 75HP injector are the largest size we recommend with the stock turbo.
