i just recently bought an intercooler upgrade and now my car smells like its running a little rich would i have to re-tune my car because of the size differene(intercooler) and trust me my first intercooler was pretty damn small compared to this new one.

 

any help?

 

when i went from a sidemount and small ic pipes to a front mount and 2.25 in pipes, my a/fs jumped up about 1 point.
you car would be running lean if anything, not rich. i think you would be safe adding about 3-5% of fuel or retune for that perfect a/f
good luck!

 

yes, retune
