Yes I understand that that's why I said I may be asking a bite much out of it but on a different note I also have a freightliner with a 280 Cummins 9speed 68000 gets 6.5 no problem at all.... but I believe I got more when I first got the mack just can't remember I usually keep up with this stuff to check back on ..I've talked with mack about a little bump in power they say if mack approves of it I think it was like 179.00 to hook it up..but for the most part I'm loving the truck looking at 1 more 2000 now..

Driving the dump truck today out the blue starts to smoke white smoke skipping running rough..tried the codes i get 6/6 fuel control module but if that was the case would the truck run at all..how can I check the injectors..it has the eup injectors as well as the others i guess is a good way to word it..

Ok guys went had both my dumps rd688s and rd690 a.c. service 688s blows but not the best 690 does not blow cold at all..both was charged and checked by a shop so I'm thinking that the units are dirty and need cleaning from dust and whatever else..so my question is where do I start and what do I need to remove. To clean the evaporator coil..
