OE tune complete

Went with the OE tune by MM in Gilbertsville, PA with addition of K&N filter system and must say it is exactly what I wanted. After a great 100k of standard power, it is like a brand new car with an undeniable power increase. It makes my daily 100 mile back road commute immensely more enjoyable; where I have been finding that second, third and fourth gear are other car quick. Gas mileage has remained the same and in general the car is simply...optimized.
