Better than expected results. 2020-year model ... 26K miles with Livernois 93 octane tune, NGK colder plugs. Very noticeable difference from stock.
Ironically, I sprayed a can of CRC Intake Valve and Turbo Cleaner through the intake. It threw three SES codes. So, I sprayed CRC MAF Cleaner on the IAT sensor, which looked a 'little' dirty. Kept looking for the MAF, however, no luck finding it. Come to find out, the IAT and MAF sensors are one-in-the-same. The sensor performs both functions, which I thought was very unusual.
After cleaning the afore-mentioned sensor, I cleared the codes with the Livernois tuner and the engine woke up in a very big way. With only 26K on the vehicle (2.7 Gen 1), thought there would be hardly any carbon buildup. I was wrong. Very impressed after spraying the CRC cleaner through the intake and the MAF cleaner across the IAT/MAF sensor wires.
The lack of port injectors must really cause a LOT of carbon buildup on the Gen 1 Ecoboost engines. This thing is a different animal now.
