I’ve always been an LS guy but purchased a 16 SRT back in March. It’s been a fun car and I absolutely love it. Was wanting to do some performance upgrades this winter. Was thinking long tubes, cam, and maybe 100 shot. Any advice on tuning, converter/trans, heads, fuel or other supporting mods is greatly appreciated

The Hemi engine uses a Speed Density system for engine control rather than a Mass Air Flow (MAF) system like the LS engines. Therefore, the Hemi is not self-adjusting when modifying the engine ... you have to update (tune) the PCM to modify the parameters (speed density table values).
DiabloSport tuning devices are popular for Hemi engines. 2019 PCMs are software locked so you also need to purchase a unlocked PCM along with the tuning device. DiabloSport tuners come with some standard tunes for bolt-ons but you will need to purchase a custom tune for long tubes, cam & NOS.
