Got It all installed and 6 mpg increase

[MD KINGRANCH]

Well I finally got it all installed. The DPF/CAT delete pipe was a PITA I hope I dont need to go back to stock anytime soon. I only ran the 275 tune so far and have been 4 tanks of diesel and mpg has been better than expected. I was getting about 11.5 prior to install now average with the 4 tanks has been 17.5 both are hand calc. weather is pretty nasty out so have not had a chance in the install to get on the pedal yet but looking forward to it. Also if anyone knows of an easy way to get to the top bolt on the delete pipe to the down pipe and also an easy way to get the pipe all the way into the muffler pipe. I ask just in case I have to reinstall.

I used a combo wrench and a ratchet with a 6" extension and wobbly....it was a PITA!!!
Have someone else help hold the muffler side while and wiggle it all back in there!!! hahaha.. I have to keep my DPF/CAT because we have emissions here in Az. I will let you know how it goes on the reinstall....

Hope to have the same results. I should have mine by this weekend and installed early next week.

I was pretty happy with the new mpg. I was hoping to get 3+ mpg increase so 6 is great. starting tomorrow I will load the 310 tune and run 4 tanks through and see how that turns out. then after that I will try the same with the 350 and the 250 as well. Will let everyone know what mine does.

The 310 is pretty wicked for a DD tune IMO, you may like it but, damn! The trottle is sensitve to the point that it would buck over bumps and such trying to DD with it.The 275 is what I DD with and it is better than the 300 and 310 in how smooth it is on and off the throttle and while using the cruise. Your truck may be different though. nice mileage though!

Using ratchet straps to pull apart or together helps. Once you put pressure pushing the two pipes together then tapping with a hammer makes the build allot easier.

Ditto. I put a good amount of tension pulling apart with ratchet straps and then just wiggled it a little and it came right off. Same putting it on, just good tension pulling it together and wiggle it a little. Mine has 2 years and 67K miles worth of grit and crap but this worked good.

Taking it apart seemed simple.
But jesus christ putting the replacement in was a PITA alone.
