Got my truck back from my shop after doing my full EGR delete and it seems like it is running lower boost and missing a few horses than before. Is this normal? They rechecked all the boots and clamps. The EGR is still in and plugged in, but the uppipe was changed and cooler deleted? No codes/lights. What else could cause this?
The connector is good and working. The shop even repaired part of the wiring harness going to it. Before the EGR delete, it would make upwards and sometimes over 20psi boost. Now i can hardly get it over 10 pounds when i put the skinny pedal down. My 03 did the same sorta, but i blamed it on not putting the new uppipe in. I am stumped on this new one though.
