I have the p0299 code ( under boost ), I replaced the diverter valve with a forge splitter valve now two days later light is back on. Would the blow off side be setting the code now since I don't have a chip or anything? Or do I have a boost leak somewhere in the boost lines?

 

u did install it upside down right. I remeber reading something about those dv's needing to be installed reverse way then the stock dv.

 

Yea I followed the instructions, which really just showed the way it flows
