1999 ws6 tuning
i got a hypertech 3 for my car from a friend was wondering the best set up for programming my car. The power tuning rfg or non rfg fuel.shift points and firmness.Thanks for any and all responses.
the rfg is for reformulated gas. depending on where you live
one could be better than the other. it will be kinda hard to tell the differnce though
a hypertech does not do much. especially for what they cost.
