So it does this automatically? Is there anyway to override it?Iam sure the EGTs were low. The 6 Gun uses a pyrometer lead and slowly backs down fueling as EGTs get closer to 1350. It works too. I had one on my 03 for a short period of time and I could not get it over 1325. I ditched it because the 6 Gun on the 03 Cummins had a surging problem with cruise on and it just was not enough power for me.
