Who's good on series 60 around St. Louis area?

We just run local, mainly MO and IL and was wondering if anyone knew someone who was really good with these engines around St. Louis area. (DDEC IV and DDEC V) We do the minor things but can't afford to go to Freightliner for engine work.

Thanks.

 

I didn't check it exactly but it seems high. We had them look at a 2005 Columbia with a 14L 455HP DDEC V that is getting bad fuel mileage, they did a few tests, (told me no engine codes, (which I had already told them due to our prolink) did a cylinder cutout, etc) put on a $56 barometric pressure sensor and charged $500. It did not change anything other than lower the checking account by $500. It sounds like from what I read on these posts Rebel127 is the guy to improve mpg on a DDEC V.

Thanks.

 

Hey Rebel127,
I had a question about charge air cooler leaks. People keep mentioning that as affecting mpg. We hooked up our Prolink and took the truck for a test drive with a 53' rail van and 40K lbs. Going up hills with engine at 100% load turbo boost pressure was 39-40psi. That seemed really good. Would that rule out a CAC leak or not really? My mechanical expertise lies more in checking lights and tires!! This is an ex Penske daycab (Actually came out of Tri State Quickrete in NJ) so it doesn't have the top air fairing and cab extenders but we are planning on putting them on. Even with that, currently we are getting about 4.5mpg and we really want to be around six. We are empty half the time and our 2003 Columbia (Old Heartland tractor can get close to 6.5mpg.) An ECM tuneup sounds like the way to go.
thanks
