I recently got the giac chip for my car. Soon after i noticed a big boost leak after checking it out with a computer. I also noticed the air flow was way down. It also idles kinda rough when i first start it. Any suggestions on where to start? Diverter? Hoses?

if you know anyone with an automotive smoke machine, those work great for finding vacuum leaks. If not, you can go pick up some carb cleaner from the store, run the motor and spray the carb cleaner around any possible leak areas. Dont go crazy as carb cleaner is VERY flammable, but if you notice the idle raise when you spray a certain area, you sir have found a vacuum leak. First areas I would visually check though are the TIP, DV, vacuum line going from intake manifold to DV

there are three hoses you can check, one on the turbo side and two on the intercooler side. pull them out and see if they are broken or have some kind of damage to it. if not, let us know.
