So, I have to refrigerate my catalysts to Save the Flatulent Whales or whatever? Only change to the car was changing the engine, transmission, and rear end oils.ĭropped 18 hp (you could see on the graph where the fuel/air ratio went nutso.) If there is a danger of overheating the catalytic converters, here's a clever clue: USE BIGGER ONES, MOPAR. I am curious just how many other controls there are that it uses to kill all possible fun in the name of reducing warranty claims.

Until you do, you are going to find your car is being choked by the stock PCM. I don't needs something threatening to go all China Syndrome under my car if i lay into the throttle, no matter how much I like clean air. So, if you are going to run your BONE STOCK HELLCAT on the dyno, I suggest you don't.įirst, get an aftermarket PCM with a tune, and for God's sake dispose of the Catalytic Shriekers. At least it didn't fluid-lock the cylinders with one quart per stroke and bend a connecting rod. I thought, 'wow that oil must suck' until the dyno guy pointed out that the second run, the A/F ratio absolutely plummeted.Ī/F ratio was hideous after a certain point. Then, to fully vomitize the dyno pull, it started barfing fuel like a sick drunk to cool off the precious catalytic converters, and chopped 18hp off.

Next run, it was in Check Engine Crisis mode, and had to pull fuses 5 and 6 to get it to quit acting Amazing in the Desmond sense. So, pulled out FUSE NUMBER 36, and were able to run full throttle.

With disabled traction control, did all we could with the cockpit controls, and the car was massivly applying rear brakes. YES, WE DISABLED TRACTION CONTROL MANUALLY IN THE ON-SCREEN MENU BEFORE STARTING.
