I would not think a flash would effect this.
Your right a flash does not change the S/W settings. If you use the "W" winter setting it is more sluggish. The "S" setting is the way to go for speed with the flash, sprint booster and other 265 kit modifications.
One thing you really feel is the car pulling like a turbo when floored at 60-70 mph. The larger injectors really kick in then and push you back in your seat.
