Ok, lets try this again. I just installed Julio's PAC kit, easy install, easier than replying to this post. First pass car hit 17# of boost NO kNOCK, easy right, turned up the boost on 2nd pass, spun tires and 60mph and hit 27 # of boost with NO KNOCK on 93 octain. All this with a street chip, I can't wait for the alky chip. Julio's PAC kit is by far the Best thing I've installed in my car. Julio's product and support is first class all the way. All there is left to say is, Thanks Julio! Way2qwk, your car will feel like it's on steroids....Good Luck with your car......Hang on and pay attention it will get loose.
