intake
 

I have a 91 tsi, and just wired in a 2g mas with a new nice hard pipe. It starts, and stays running, yet runs lean and i get the check engine light, was wondering if anyone knew if tossing some 660's in would cancel it out and run normal, or if maybe not sodering properly would make it run bad, I also have an safc ready to be wired and needed some help with that, let me know im kind os still new to this, thanks

Check out the www.vfaq.com for the wiring issue.

Usually 550's will cancel out a 2g mas pretty good. a SAFC would be good to fine tune though.
