Yes it is deleted truck. When old turbo was fine it use to run fine. Going to take it back to get a exhaust and boost leak check and VGT calibration checked. I tried myself to check for leak. I found exhaust leak but still cant find boost leak

You know the sound when air leaks thru a small pin hole. I can hear that sound. But i cant figure out where its coming from all my pipes and clamps are new.

Its a 2014 mack chu613 with mp8. I just got new turbo and now truck blows black smoke when up shifting and speeding up. Its fine under normal driving.

Hello did ever fix it. My mack has a new turbo it also blow black smoke between gears.

So i got my truck checked. The intake air heater was bad got it replaced and tech put ome more power cable direct from battery. So far truck start fine but it has not been very cold.

Hello everyone, My truck 2014 chu613 with mp8 engine has cold starting problem. When i turn the key on in the morning after truck has been sitting off for whole night at first my tail lights and backup lights will blink 5 to 6 time . Then my dashboard will flicker 3to4 times before it comes on. Then when i try to start the truck nothing happens .when i check engine hours there nothing there. I had to cycle key on and off many times to get it to start. It does start thou. But when truck gets to operating temprature it does not have this problem it start right away no problems at all. It is deleted truck. I think ecu is not getting power or EPDM has a problem. Any sugestions
