2018 SRT Demon, 2011 SRT Challenger
I have a 2011 SRT Challenger with just 21,000 miles. It’s twin turbo’d and has a custom tune. Bought from the original owner who didn’t have the engine built to handle the turbos. Brand new engine rebuild with forged internals. I am running the 6.1 intake for a bit better torque curve. Car ran great before the rebuild given it had a few scalded piston tops. This is the problem I’m having. On cold start (in Florida no less) it starts right up, but then falters and stalls. It takes 3-4 starts before it warms up enough to get a good idle. Car runs fine around town, but haven’t gotten on it yet. Here is what I have addressed so far. New fuel pumps, new two bar map, new water temp sensor, new cam sensor, new plugs, new injectors. I have a periodic code that says bank 2 is too rich. I haven’t changed the O2 sensors on the right side yet. This is getting frustrating as I’ve tried nearly everything to get this engine to have a normal startup. If anyone has any ideas I would very much appreciate your help.
