i've had my supercharger installed a couple of weeks but now all of a sudden the check engine light is on . i pulled the coades and it read p1151 lack of ho2s21 switches-sensor indicates lean. is there anything that i can do to correct this problem, i am having it tuned on the 27th of this month. or should i wait to get it tuned and let them fix it and will it be ok to drive untill then? please help!! thanks...

id just wait until you get on the dyno. i wouldnt run it if its running lean. if you got vortech tune then thats your problem, i hear they arent very accurate. if youre not pinging or anything you should be good to drive to the dyno, as long as its not like 4 hours away.
