If the washer fluid tank is dry, aka meth tank, then it's possible the previous owner ran it dry and returned car to stock tune before trading in. How long have you had the car? If you have done some significant driving with no issues, that may be the case. If it's tuned for meth with no meth, you'd have problems. Best thing would be to have dealer confirm whether or not tune is stock, if not return to stock. Then get in contact with LMS or unleashed, get a tuner with a meth tune, then buy some meth, and finally enjoy your fast SHO!
