supposedly this guy has a gst ..all stock..just a boost controller, he said he boosted to about 14.5 or 16.5(can't remember which one) and ran a 14.2 in the quarter... is this possible? boosting that high on a STOCK car??

 

its possible, my buddy with a 98 gst is boosting 19 lbs. he did it by accident but he runs ok for now. so around 15 lbs. is ok for a stock mitsu.
