Aftermarket Mods 2019 E450
I would recommend the Racechip module. On the 2021, which I have, it needs to be installed by a professional.
I think the 2019 still has the V6, not sure. If it's that engine, the installation should be far easier.
I had the 2018 E400, and the installation was a snap.
The power increase and torque was fabulous.
Would also recommend the throttle chip. With or without the engine chip, the response improvement is uncanny.
