Let me put it this way, about 75% of all our Evo XEDE customers ask for both pump gas and 100oct race gas maps when they come into the get dyno tuned. Depending on the turbo in the car, the race gas map is worth 40-100whp more than the pump gas map. On the good stuff, the cars run cooler, happier and a helluva lot stronger. They toggle over to the race gas map when they go to the drag strip, track days or even... ahem... street races. It's their secret "equalizer" when it comes to going up against the bigger boys.
I'm eager to do a 100ct map with my 335i. I just haven't gotten around to it yet. I'm guessing it'll hit 400lbft of torque at the wheels without any problem. Peak hp will be limited by turbo capacity but I'll be dissappointed if we don't see 370whp.
Would it make sense to have a seperate map for those of us that live at high-altitude? I for example, live at 4,500 above sea level. The atmpospheric pressure here is about 12.5 psi versus 14.7 at sea level. Will the turbo's fully compensate for this decrease in air pressure or would it make sense to have another map that would add 2.2psi of boost across the rev range to help compensate? Thanks!
