has anyone used a g tech pro ss because im having trouble calibrating the ignition part of the setup, does any one have any helpful suggestions. and it also seems very inacurrate because on a real dyno my car reads 110whp and 109 ft/lbs tq but the g tech says 85hp and 127 ft/lb tq. i set the vehicle weight at 2650 w/me and a 1/2 tank. this might be the wrong section for this question but i like this crowd.
