Did you know that our 6.7 Cummins S300 kit can increase your fuel mileage?

We all see how high these fuel prices have gotten, and we all know the performance benefits of the fixed geometry turbochargers, but something we don’t touch on often is fuel efficiency. This doesn’t only go for the Cummins platform though - we’ve seen fuel mileage increases of 2-5 mpg among all platforms who run a VGT and convert to fixed geometry s300 turbochargers.

No one is immune to these diesel prices, and everyone would love to have a lower fuel bill. Let us help you gain performance and fuel efficiency all in one.
