2003-2007 5.9L DROP-IN CUMMINS TURBO:
After the extensive testing we did in the Cummins Turbo Shootout back in 2013 we learned a few things about Cummins single turbo systems. This test featured 5 turbo's, recomended by the manufacturer, analyzed and compared side-by-side.
If you read the article featured in Diesel Power Magazine or listened to the episodes we did at the Diesel Performance Podcast then you already know there was no clear 1 winner. The reality of aftermarket turbo's is you have to sacrafice something to gain something. So we set out to develop a turbo that could meet our requirements for being a great daily driver, good for managing EGT's while towing and something we could cause havok on the streets with.
