Like many I opted to not go through the recall as the majority of trucks that have had the "upgrade" lose performance and mileage and are often times difficult to drive due to extreme delays in throttle response. The strange thing about the upgrade is the inconsistency reported by owners who's trucks have gone through it. Extended warranty aside, the better option in my opinion is the GDE or other aftermarket controller upgrades rather than the "factory" upgrade.
