Ok, I am having a problem with my acceleration. I step on the gas and nothing....I have to pull over to the shoulder and let off the gas and very slowly start to accelerate. In that time I hear no turbo whistle. When I reach about 30 to 40 mph my turbo will kick in and then I can start moving along again. I also am experiencing the same when I am towing my 5th wheel when I need to go up hill. I step on the gas and my truck starts to lose power I let off the gas and start again and it starts going again. I have a 2004 Ford F250 6.0L, egr delete, swamped tuned FICM, ARP head studs, AFE intake (came with the truck), MBRP 4 inch exhaust, and edge tuner. I have not yet had a chance to get to the shop to have any diagnostic work done yet so I do not know if any codes are present. I have read that my turbo might be sticking. Just thought I would ask to see if there might be anyone who could help without me having to take it to the shop. Thanks

 

codes help alot...try auto zone or advanced auto parts for a free code reading...scott

 

went to Autozone yesterday and there OBD said 0 codes. It seems kind of weird to me though because since my EGR delete I have always had some type of code about at least that. Not to sure other than to take it and spend the money to get a full diagnosis ran.
