I want to see what it does on street tires from like a 20MPH roll, that is where the real money is for most of us guys. Getting on the freeway and shaming a EVO next to you or something.
And to the comment about having it make so much power its not the same car, there is nothing wrong with a surplus of power as long as you are prepared for possible consequences like picking your crank up off the road. Otherwise its fun to have a car that makes almost double what it originally did and just running it around on a very conservative tune until you wanna unleash the beast. I dont see people with 800HP EVO's complaining, they dont daily them with that much power usually, its often a major detuned map that makes good power but is liveable and driveable.
Taking a FiST and having it produce near as makes no difference 350FWHP and 400FWTQ (for example) would be impossible to drive all the time, it would incinerate tires at every stop light. But a FiST capable of that and running a tune with only say 260FWHP and say 300FWTQ, that would be fun and possible.
