What car?Mackattk said:yes its turboed or i wouldnt have a boost controller
:facepalm:Mackattk said:its an 03 wrx, when i got it the boost gauge read 6psi of boost. i heard it could run 15psi but its had some problems that i just fixed and i dont want to dial it up to much and blow the engine.
You didn't fix the issue at all. You stuck a bandaid on a wound that requires stitches.
An '03 WRX is targets ~13.5 PSI in stock form.
Remove the MBC and replace it with a stock BCS. Fix whatever is causing it not to hit target boost, then consider upping the wick.
