Default Re-Tune After intake??

So I already have a tune on my car (mods in sig). If I added a FAST 90/90 w throttle body would I have to re-tune?...Or any problems added them with my existing tune??? I do have a AEM wideband to see what difference it would make...Anybody have some experience?

Recommended but may not be necessary. You will only get the full benefits if you get it tuned again though. Could maybe get away with it though since you already had a tune, and realistically you haven't changed anything else. Watch A/F ratio though.
