first of all get rid of that missing link...there not worth a shit. Then get the car tuned...it should run you around 300 plus maybe a little more if your ecu is a virgin. Dont try and drive around boosting when your car is untuned. It sounds like your still using stock injectors? Otherwise it probaly wouldnt run good enough to drive period...if you are then thats a big no no! Go get it tuned and then you will be problem free!
