How much vaccum should I be running at idle on a stock 1989 5 speed? And how much boost should I be running stock? The only thing that has been done to the car that I know of is the peice under the air box has been removed.
Also how accurate is the stock boost gauge? Should I invest in a good aftermarket one and where is the best place to hook it up if so?
Thanks
