Ok I installed a new clutch and when i fired it up it read error code P0243. The car drives fine in dd but when I try to gun it it backfires like crazy and wont go further than 15-16 psi. Ive searched the forums and found that it could be the factory boost solenoid not plugged in correctly or could have given out there are several reasons. Well when I tried to look for it i couldnt find anything that resembled the picture. A friend installed my mbc so im assuming when he did the fbs was taken out? My mods are listed on my sig. I dont know if that would help. Thanks in advance.

 

anyone?
