Hey, I wondered if anyone knows what is involved in the TSB that swaps out the original IC for the up-dated one? I read somewhere that the newer one is smaller and keeps the temp up high enough to keep condensation "burned off" and naturally wondered if smaller was not as good as what I have now for performance?? Making plans to do the intake and tune her once the warranty is cooked (won't be long at my current mileage rate).
Got mine done one mount ago. Up to now it fixed the problem but I really don't like it. It feel like I lost 50 hp especially in low to mid range. The fun with the ecoboost was the low end torque that allowed the transmission to stay in high gear and when you push the throttle you were able to feel the boost and go... This is now over. They probably recalibrate the transmission also because it now down shift all the time. The "day to day" fuel consumption as also increase, I was normally averaging 15 liters/100 km 15.7 miles/gallon(US) and now I can't barely keep it below 18 liters/100 km = 13.1 miles/gallon(US).
Hmmmm.... now I wonder if I can just cancel the idea of swapping it out? I don't have the stumble often enough to warrant losing power and mileage! Now that I have been to the dealer to whine have the wheels started to turn or can I back out? I'm gonna call them and check.
