Tuner Basics?

[Spl170s]

recently purchased car that hasn't been tuned in about 2 years. Car has aftermarket mods. In dire need of tuning. I am new the turbo world and would like to know where to start with such a project. Currently on my scanmaster, i cannot really get into this car without alot of knock occuring. I know my IAC is off, as well as the car didn't have a AFPR before. I am installing one tonight.

The car was tuned when built 2 years ago.

Why do you say your IAC is off? Have you checked out the spring cleaning section @ GNttype.org ?

My IAC is reading 00 on the scan master. So i am guessing it was off. I did the readjsutment procedure on that site and get it set right now.
