    make sure the pipes are not plugged to the delta sensor, other wise weld the egr valve closed, an fool the ecm by reducung the voltage from the barometric sensor to les than 2.5 volts back to the ecm, i found this solution in this forum, i have not done it yet, i do have the parts ,just need the time to get it done,, good luck
