Ok, then see what I posted above. If you are planning to add boost, tuner style aint the way to go with a stock turbo and stock actuator. I personally think that cranking down on a stock spring actuator more than 5 lbs or so is stretching it and you start to lose control.
You should make a known chip purchase a priority. A $25 Thrasher is a good start and a good street chip. Also, I hope you are using a scan tool/ knock monitor before you start playing with boost.
