hello
can some point in the rite direction for a gear ratio with a 17.5 i am running at 4.5 at the momant and during testing it doesnt seem to be very good.i copied a programme form the speed passion site but i dont notice any boost at all. the motor timing is standard at the momentas it came out of the box.

i am alittle confused at the moment trying to catch up on technolagy not raced TC for 4 plus years

thanks
