msp chris sorry i have been really busy this week at work to reply back to you. the difference you will see is in performance of the car. i don't know if your car feels slow after you have driven for an hour or so. but with the fmic from spool there is no slow feeling. the colder the charge going from the turbo the the engine meens more power. the car spins the tires right much now in 1st and hard in 2nd. the car also has mbc , fuel reduction kit, and air intake.
