i just installed my boost gauge and put the stock wastegate back on b/c the adjustable one it had was not adjustable was was adjusted to boost too high...it was seized...anyway...with the stock one on it shouldnt ever go above 15 psi, correct? i dont know if this is true or not but that is what i thought and i saw it go to at least 20...i got off it right away...it also starts to ping around 15, that is why i would like to keep it within the stock limits until i figure out what is going on. I ordered a Walbro 340 and booster kit...i hope that this will help the fuel delivery...please help because I would like to get this thing running at its best. what could be wrong??
