For what it's worth, I decided to give Livernois Motorsports Tune a try as well, like OffTheWall503. Called Anthony from Livernois regarding the Tune and had a good 15-20 minutes chat about the Tune, their usage of MyCal and the Ecoboost platform, as well as Torco additives. A friendly and detail oriented guy. Does not talk to you in a condescending manner.
Had a chance over the weekend to drive it around and see how it compares to Stratified and allow time for the tune to adapt. I used 92 octane with the 91 Tune. I have the Mishimoto I/C as well.
So, for everyday driving with gradual push of the pedal, it behaves very much like stock. The Stratified was a bit more peppy in everyday driving, in that sense. Now, when the pedal is pushed > 50% in a quick manner, WHOA, the Power Band is more broad from 2500-6000 rpm. Does not have the "Donkey Kick" sensation and does not run out of steam after 5000 rpm. The pull is very linear, but forceful. It feels like the car has another cylinder put in. Just a good amount of pull from midrange to redline. No fuss, no must. This Tune may just be the most well kept secret and underrated thing! Makes driving the FiST that much more enjoyable. There's no Rev Hang, that I could discern. Shifting is smooth, similar to Stratified. Stratified is great and I love their tune, but Livernois did something that made the FiST even better, IMO. I am quite surprised and pleased.
