anyone using h&s xrt tuner

Anyone using h&S xrt TUNER? Im also looking at an mbrp 4 inchlift exhaust. Want to know if it helps with the mileage. I got a 6.6 lmm with 4 inch lift 33x12.50 r20 wheels

Not sure on the tuning but if the mbrp 4 inch exhaust is DPF back it is just for looks. You would need a full DOC and DPF delete to see any MPG.

I've used the XRT on quite a few Dodges with great results.

I haven't used one on a Lmm but have lmls they run very good Dodge and Ford trucks run very good as well. I'd go with a mini Maxx at least or maybe see if you get some Efi live from someone close yo you :thumb:

finally got off my butt and got a H&S XRT tuner and a 4" inch mbrp turbo back exhaust. Felt a difference right away im making between 17 and 19 mpg!
