Just wondering if anyone has the new mp8 programmer from ts performance. i heard there suppose to be the best out there for then new 6.7 cummins. if anyone has one i would like to know how you like them. thanks. oh yea im new to the forum and just thought id say hi to all my cummins bros out there

 

So how do you like the new 6.7? I'm not to sure about the MP-8. I know it's one of the few boxes out there on the market.

 

Thats the only thing ive sold so far for the 6.7L and people love them.

 

Other than the mileage my 6.7 has been great........

 

ya the mileage does suck compared to the 5.9s but i love it. just need to get rid of all the emissions stuff on it

 

i have the mp8 on my 07 3500 and its great. the fuel milage on my overhead went from 13 to 14.5 to 16 depending on driving habits. the power is quite noticable but not overpowering, one bad thing my clutch is slipping really bad now with the chip. south bend can take care of that though. what kind of fuel milage do you get stock?

 

I have nothing but good things to say about mine.

 

i was gettin about the same around 13 or 14 around town and i got about 16 on the highway

 

have you used yours to tow any load and if so what fuel milage did you get? and one other compaint, its not fast by any means, my old 6.0 ford was a race car compared to my new dodge. however the ford couldn't go a month without blowing head gaskets, hince a cummins in the driveway now.

 

Hmmm. I drove a 6.0 Excursion for a while and it was very slow. Much slower than this truck, that's for sure. Unless your 6.0 was modified...
