Hello. I’m new to this forum and the entire tuning world altogether. I have a few questions.
First, how should I start getting into tuning? What concepts should I start getting comfortable with?
Second, my 2018 Wrangler JK doesn’t have a MAF sensor and I’m thinking of installing a cold air intake and tuning. Do I need an MAF sensor to tune the CAI or can I go off speed density.
Third, can I install extra accessories on the stock ECU? Can things like an MAF sensor and a wide and be wired and monitored by the stock ECU, or do I need an aftermarket PCM?
