how many miles on the old car? im at almost 80k in 6.5 years. i want an 18 but money is tight due to changing jobs. i am surprised you never replaced any of the blend door actuators as i have had 2 fail now.
just an fyi the ford esp plans are a great investment for the biggest failures, that being the ac system and the navigation system, neither of which would be affected by a tune.
Just because you mod doesnt mean the extended warranty is a waste. I had the ac compressor failed in my 2011 gt last july at 60k miles. Repair was fully covered. Cost me nothing. Out of pocket would have been 1500.
From what i have read the 10 speed has 4 overdrive gears meant for turning lower engine rpms on the highway. I would imagine the mpg rating should be close to 30 mpg highway.
