Hello guys 

ive got a 97 Mack rb with em7 300 mechanical motor I took it to mechanic had the timing advanced and little fuel turned to it. I brought it back home put a new 400 turbo on it. I was wanting to turn more fuel to it. It's got the Bosch pump its only runnin about 800 deg on pyrometer loaded on long pull.  We do most of our own repairs but never been in one of those pumps. Thanks for any advice.
