Yeah , u can do stuff like changing elevation, ambient air..........just small things that will effect the outcome......for instance, once on the dyno my friends car puts down a legitimate 921rwhp..........with some small altercations to the elevation.......he was putting down around 1200......i dunno, i just don't think its cool if when shops lie about numbers
