hello, noobie here. wondering if i could get some advice.
i have a fmic, intakes, radiator, downpipe, and catback to be installed. do i need to install a standalone right away? or can i hold off for a little without messin up my engine.

thanks

if you keep boost in check, and keep the cat on...you should be fine.

only way to tell for sure is to put a wide band O2 on and see.
