Ive only gteched it. I dont want to wait in lines to run it in the heat.
When the winter comes around I think ill run it just cause.
I still believe mags are relatively accurate. Hell you have the other side of the coin. some publications uses NHRA drag racers who speed shift. I remember they were pullint high 12s with Camaros..
So maybe they are accurate sometimes and not other times, but it could be both ways.
Still they are using actual test equipment
