I put the dynatech system (long tubes and the 2 high flow cats) on. Had read when you do you have to turn off the rear 02's with Pred. Also heard you didn't have to. So I didn't, and after just a few drives the truck seemed to be idling a little funny? Well tonight got the thrown code. Which brings me to the Predator ? When I got to the 02 adjustment screen it was already highlighted NO, then there was Yes and no change. Same applied to the heater bank adjusment page with NO being highlighted already which it reads those have to be turned off also? Just wanted to ask as to not screw up my custom tune. Appreciate help.
