Any help is appriciated
Could this be the result of a bad tune?

sounds like it could be a bad tune.
your ecu tune can have a lot to do with it running rich like that. i remember when we had a cavalier... after we dropped a gtp sc into it, it ran soo rich that fuel dripped from the tailpipe.... not cool lol

yeah my car is shooting flames sometimes too, this is probably a tune issue

b18b on boost doesn't many people help you figure out whats wrong with it lol.

should get into more detail with the actual setup.
who tuned it? or you just slap a chip in it and run a basic tune?

It was tuned by the previous owner at maxwell, and the setup is garret t3/t4,stock internals, turbo xs BOV,Turbo xs front mount,turbo smart manual boost controller,
