how would i go tune my 342? not firmiliar with this.... does the shop tune a chip and install it or do i have to buy a programmer to tune it or is there a computer that i can use??
If you find a local shop that has a dyno most have chip burning capability, dyno and tune will cost ya $500-$600 and will give you no adjustability, but they can burn multiple programs if you plan to run N2O or other.
The chip is the most cost effective for most, after that you get into handheld piggy back tuners like a PMS ($1000), Moates Quarterhorse, etc.. You will need to make sure the shop who is tuning the car can work with what ever tuner you decide on. If you do not know what your doing, Id recommed a chip, the other units can get you in trouble fast if your not careful.....a blown/broken motor is only a click away.
