This week at CR Performance Engineering Inc. we have just completed our first off of the 46mm/56mm upgrade for 2018+ for 3.5L F-150 EcoBoost.
This is a excellent upgrade from 40.8mm/51mm stock setup and retains excellent spool times and is designed to be fully towing compatible with a excellent surge margin and will be well balanced in combination with the 2018+ MWE Map Width Enhancement Groove seen on these BorgWarner turbochargers.
More details to come soon with the official release!
