Hello! I am new to this forum and am hoping someone can help with an ongoing issue. I have an 01 F250 that I De-Stroked with an 03 Cummins about 8 yrs ago. The donor truck had a 6spd transmission in it with the APPS under the battery.I have the Ford 4R100 transmission. 60hp injectors, Smarty tuner. I also have an Edge monitor. Nothing real fancy. When I go to WOT the truck falls to idle for about 20 secs and then drives normal. I don’t get any codes that the Smarty can read. I have tested the APPS and it seems to be working perfectly. The rail pressure doesn’t go over about 23K. I am open to any suggestions and will answer any questions that help me come to a solution.
Thanks again for all your help with this.
