I have 93 GT, for the most part completely stock, other than an explorer intake and cobra rockers. The car came with a powerdyne kit, uninstalled, but almost complete. From what I can see it was done over by 928 Motorsport, I stumbled upon the receipt in the trunk. The install was pretty much a breeze except some bolt were missing but it's all sorted out now.
Now, my concerns are regarding the blow-off valve that's on the intake pipe, I'm a newbie when it comes to forced induction. It seems like there's a knob on the valve for adjustment. From what i can understand I close the adjustment, the less pressure if relieves, right? I am yet to install a boost gauge and a fuel gauge, just to check and make sure, but I'm also trying to figure out what's causing the surging idle since the install.
