Good news as it seems it is at least indicating miles per gallon are going the right way. I only wish you had a gauge installed so pressure at loaded speed could be known. Also at pre spring stretch setting. At present we are somewhat handicapped until Yellis (kevin) reports the results of his efforts as he has a gauge installed. Or indeed any other posters with a gauge as well.

If you get a chance. Can you talk to the gentleman you stretched his spring for and his shakey idle was history? With that much improvement there might be a milage or power boost he is noticing. Maybe both. Actually it is a forgone conclusion they both will be better even at this early stage. You probably have made him quite happy. We really do need all the information we can get at this stage. Nice to see some people really starting to get into this. Pretty soon it will self sustain I hope.

I am still waiting for the first 240d to increase milage from about 25 to 30-32 miles per American gallon. Hopefully the individual will install a pressure gauge before he starts and seek 20-22 pounds fuel pressure under load if his is curently less. Almost bound to be less in my opinion. There will be a power increase as well not that it is needed.

I feel if there is resistance to joining the something for nothing club it will stop at some point. Hopefully people will approach this area with a gauge. Only restoring function to high normal as well when burning diesel fuel. Until more is learned about further elevated pressures than are recommended at this point. It may turn out they are quite safe. Or require other minor changes to be safe. I for one do not know that information at present.

As an additional incentive I hope he thinks positive and wants to protect his number one rod bearing on his 616 as well if that pans out.

One gentleman is going to examine his spare injection pump this weekend if he gets time. He hopes to determine if indeed the number one injector sees the highest portion of the constant pulse when running.

That information would really be appreciated by a lot of 616 owners like myself. Strange but I suspect he will find the number one pump element is at the high end of the pulse. Could be wrong though.

The entertainment value of this thread as a possible item itself might be working out. We seem to be attracting more than a few observers. . We need gauge readers now to move ahead. Why not just check your operating fuel pressure under load?
