Well, I finally did it at 46,500 miles. Had the Black Maxx installed today with a full DPF / EGR delete and new exhaust from the turbo back. Can't wait to test it out. Stepped on it (in "mild") and everything in the cab went flying to the back seat.

Sounds great (not louder, just better and throaty) and has lots of go set on "mild". The shop also put on a leveling kit and the truck sits better now.

Looking forward to better mileage (and blowing by the Father-in-law while going up the pass and pulling our 5'ers).

Just had to share.......

 

Super jealous! Congrats.

Not sure that I can wait out the remaining 20,000 miles on my warranty...

Would love to hear your gas mileage results.

 

Yeah! Good feeling...

 

Welcome to the club.....You will be very happy!!!

 

Well, I have 3 days into the improved truck. Impressed, very impressed. Its going to be hard to get better mileage than I was before, too fun with a heavy foot.

The Cummins is sure glad to exhale easy.......
