Ok so i removed a PPE from an 07.5 LMM. Installed a DSP5 tune i built. I had a mileage tune for the base tune and wanted to move it to the DSP3 position so i copied and pasted the tables accordingly and returned the base tune to stock power level. Base, DSP 1,2, and 4 work properly, however when i turn it to DSP 3 the truck dies. It dies sort of slowly not like switching the key off. I have the latest software i think, with the 34 firmware. Oh one more detail, after i built the tune with all these changes. i made a script file of it and and applied it do a stock DSP 5. I have looked over the #3 folders and can't see any problems. Used DVT controls and ran Rail pressure up to around 95 MPa and truck would run on DSP 3. I'm lost.
