Question about the performance package

[Darnellbe]

Hey guys new to the car scene. Recently brought an ecoboost and was wondering if the upgrades/mods of the performance package was worth it, specifically the M-9603-M4? Does anyone have it or know of anyone who does? If so how’s the reliability, power and gas mileage?

It’s the most reliable in terms of canned tunes imo. Maybe a solid choice with way nations being changed with epa stuff. As that’s epa compliant tune.

That said, it’s weaker compared to aftermarket. The reliability comes from safe power/holding back

I run fp, I’m happy
