Now supercharged

**duane9586** · 08-24-2008

I just got done making my 2005 base into a supercharged gp. The boost gauge is showing 3. Seems low? i have the stock pulley on it, no KR and codes for the o2 and map sensor voltage. Any ideas, I also have the breather on the valve cover...

Do you have the vacume line for the BBV connected? When unplugged it limits it to 3psi. Also i think i read somewhere that it may have something to do with the pcm...I made a point to remember but now i forgot. But maybe that had to do with s/c'ing a older model gp. I'll look now to see if i cant find it

I figured it out. I just disconnected the vacume lines to the bbv and its now working fine. Just have to try to figure out how to deal with the codes...P0030, 0053, 0131, 0243, 1106, and 0229

a top swapped car either needs a l67 pcm to be able to run the bbv, or to just run it vacuum controlled my disconnecting the lower vacuum line and leaving it open. so, good thing youve figured that out.

now fix the rest of your mess.

yes it runs much better now. i am going to replace the o2 sensor next. We will see what happens.
