What is the best way on a dyno for the most accurate test ? I think , for automatic , in 2 and then go ? or is it another way to do...?
3rd gear is 1:1 It has to be strapped down and if possible dont do it on a too hot / humid day. They will recalculate the values but still a good climate is the best way to get decent results.
Remove the kickdown cable from the TB, put in tow haul in 3rd gear, make a pull from 2000-2500 or so to 6000.
