Well, my idle fluxuates from about 750-900 back and forth( really shakey). I did take that line for the guage and it seems to be connected pretty good. When I am driving the car it will hesitation until it hits boost and then pull but not as much as it did stock. I just cant figure out this problem. I have owned two DSM and the one I sold also had bad hesitation before I sold it. I followed up on it and the owner of it now had to replace the whole ignition system and still is having problems. I am not in a hurry to sell it, but dont have the money to constantly be fixing petty problems. Thanks for all the help so far! Matt
