Cummins X15 Efficiency Series

My stock 500hp engine was struggling with my dedicated route, dallas to portland. I have the CM2350 and while it is efficient when light and level stock just wasn't cutting it for heavy and higher elevations. The bolt on manifold and tuner live up to their name. PDI was quick at shipping and customer service was helpful too. I would also purchase their turbo and manifold for the other side of the engine if it was ca. approved.

Extremely impressed

I was skeptical at first but after running it for my first week I am thinking of getting the exhaust manifold next. I run the north east a lot and with a Pete 389 I’m getting 6.8 MPG. I’m very happy with it.

Stage 1

So far I’m Happy with this purchase. I’ve gained some fuel mileage and definitely notice the pulling power. Only 2 weeks in to running it!

Stage 1 big boss kit

I highly recommend investing in this kit. I’m already noticing 1/2mpg increase at the pump and a big increase in power and drive ability.
