Just was curious if anyone with a 6.0 has had to replace the oil injection pump. My truck would run fine ,but at 3200rpm it would act like it was on the rev limiter. I had the oil injection pump replaced and the truck still acted like it hits the rev limiter ,but not as bad now. Took off the programmer and now my pressures are all up to par. Everything looks great except I don't have my programmer installed. We are now thinking the programmer either has a bad program in it or the programmer itself is bad. Waiting till Monday to troubleshoot the programmer. Just didn't know if anyone else has had this problem. Thanks.

SMOKE THEM IF YOU GOT THEM!!

 

What programmer are you using? Anything else done to the truck? Any codes being generated? IPR or ICP maybe?
