That will cause the engine not to run smoothly. It will always be under load. I would remove the actuator and move the lever while the engine is running. If it clears up when the turbo is open then the issue can be with the tune or the turbo. I don't know, just a guy thinking out loud.

Make sure you check them slaves as v mentioned! Hopefully injectors cure it how ever grasping straws and chucking parts is expensive!

Joey Mack Posted September 23, 2022 Share Posted September 23, 2022 I'm sorry, but I'm leaning towards workmanship... and I also think that it is programming after he said, the head replacement and cam timing is good... So, Dirtymilkman.. is likely correct...

So, Dirtymilkman.. is likely correct... yup it’s deleted so it’s a crap shoot !Takes your chances with this! Hopefully don’t crack the head! Seen so many isx turn in to shower heads by deleting with the wrong programming! Could be Just a night mare!

Popular Post Joey Mack Posted September 23, 2022 Popular Post Share Posted September 23, 2022 I know that I have no knowledge on how to make a 'delete' work.. because, I learned years ago, the creators of these ECM's, knew what they were doing... They are fully tied into the Govt. branches that control this "green" bull shit.. A lot of guys hear thing's on the C.B. or social media, that they can get 100+ HP, with a delete.. But what they don't know is that the people that built these ECM's.. already knew that guy's were going to try to get around the rule's... and they put fail safe's or whatever in the ECM's... I truly understand what truckers are trying to accomplish, but... it aint gonna happen... Just buy a real truck, and rebuild the engine, and tranny if needed , replace the rear end oils, and go on and make the money. I know it's easy for me to post this, but i'm right.... correct me if i'm wrong.... anyone... correct me.... jojo 2 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70446-turbo-swap-vgt-delete-mp10/page/2/#findComment-510147 Share on other sites More sharing options...

Also the issues we hear about with these deleted trucks is a lot of times catastrophic. None of these “programmers” are smarter than the engineers these big truck companies hired. These deletes have been going on since about 09-10 since the first emissions came out. The government/manufactures have got it bullet proof by now. Pay now or pay later. By the way the smoke in your vid looks blue to me so looks to be oil involved. If it’s white and I can’t see from the vid, then that’s usually low fuel pressure, low compression, or wayyyy over fueled. I think vmac is onto something though.

Popular Post Vmac3 Posted September 23, 2022 Popular Post Share Posted September 23, 2022 I also agree with the sentiment with others. Changing timing, injection metering, deleting these emission components and squeezing as much power as you can out of these engines that are not designed to do so will cause a lot of heart ache. A good example is the ASET AI engine, notice how the engine rpm ramps up slowly from idle compared to older E7 engines? You are not going to get all that power at once. Cylinder pressures climb gradually to increase longevity of these small bore engines and try to reduce exhaust emissions. If cylinder pressures peak to early in these engines, what will happen to that engine is anyone's guess. I wouldn't want to risk that, especially with the crazy cost of parts, the availability of them and then trying to find a knowledgeable wrench to work on it is going to compound the problem. Oh yah, cant forget the downtime also.

Solution Popular Post ltamikey Posted December 7, 2022 Author Solution Popular Post Share Posted December 7, 2022 Hello Again, I would like to Thank everyone for all the ideas, They were all valuable! I also want everyone to know we finally got to the bottom of it. Turns out, somewhere along the way the banjo fittings for the inlet and return fuel to the head were swapped, which meant that the inlet had an orifice inside restricting fuel to the motor and the return was wide open allowing fuel to bypass the injectors....cant believe it, but its running strong again!! Hopefully this helps someone down the road not make the same mistake! Thanks again, Mikey 5 1 Quote Link to comment https://www.bigmacktrucks.com/topic/70446-turbo-swap-vgt-delete-mp10/page/2/#findComment-517693 Share on other sites More sharing options...
