I have looked at boost controllers for more perforance, but I believe that you dial in a setting and that's your boost. Our stock controller, if I am correct has a variable boost depending upon data received by our chips. If so, does this data show what the boost is to the turbo and if it does could this boost sensor be reprogrammed or tricked into showing 2 lbs. under actual? If so, we would have the advantage of variable boost, yet higher boost throughout the range than stock. Possible or Impossible?
Why? You want maximum boost at WOT and the only thing that will limit that is available fuel and the design restrictions of the engine.
The pcm controls torque output via the waste gate. The only way to increase torque output and HP( without being reeled back in) is to bypass the pcm control of the wga. The only real way to increase boost would be the installation of a boost controller and bypass the #2 solenoid. Unfortunately this affects part throttle drivability, basically too much boost to fast which leads to "flutter","surging". However, you can use a system that only bypasses the # 2 solenoid under WOT. This has been discussed in length on this board and the srtforums board. Try searching dsabc or dual stage automatic boost controller.
A higher rev limiter would be nice!
