OK, should you do it yourself??that depends on you, if you have some mechanical ability, then it is not that big of a deal, there are several write ups on how to do this step by step. You will save a ton of money doing it yourself, take your time and do it right. Now as far as driving it without a tune,, Any good tuner can give you a mail order tune that will get the engine running close enough to bring the car to them. If not, You can get a tow truck to take your car to the tuner if he is close, for under 100 dollars,, I ASSURE YOU no one is gonna put a cam in your car for 100 bucks. Or you can rent a Uhaul car trailer for about 60 bucks a day, All You need is a truck to pull it, or a buddy with a truck. Which ever way you go, I would not recommend driving the car without a tune. Hope this helps.
