Installed the Livernois tune package over the last few days (Windstorm CAI, Evenflo 160 degree thermostat) and today I received and loaded the 87 octane (that's what I had in the tank) performance tune and 3-bar MAF sensor. VERY happy with the results. Acceleration was smooth as silk. Sport mode was noticeably more powerful. As promoted by Livernois, shifting was much quicker and more solid. The "hard shift" mentioned in previous posts was only noticed one time during an hour of so of driving and occurred only when I slammed the pedal down to WOT when some fool though he was going to pass me at a high rate of speed,,,,,,,,,,,,,,,WRONG. The shift was merely super quick and solid, feeling like a bump- not a big deal. As Livernois stated when I received the tune file, this behavior is expected initially and mellows and the transmission learns my driving habits. In Sport mode the engine braking/ downshifting was definitely more noticeable (a good thing). I love the audible inhale of the engine from the Windstorm CAI. Installation on everything was a breeze. The CAI is straightforward. As mentioned in other posts, buy a gallon or the orange pre-mixed antifreeze prior to the thermostat swap- I lost almost that much during the the swap. MAF sensor takes minutes to swap.
REALLY looking forward to upgrading to 93 octane and swapping tune files. Not looking forward to the guilt of driving like a jerk until the novelty wears off! Will update post with impressions of the big daddy tune file.
