I have had a fast 90/90 sitting in my room for a while now and i would like to put it on. Do i need to have it tuned to run this intake or will the tune i have work for now. My car is tuned for cam,ls6 intake,mti bigger throttel bodie, corsa, mac mids(im am putting kooks longs on this week). Any help would be great thanks.

It's not worth it. Sell it cheap to me.

Your car will probly run fine but a tune will help you out to get the full potential out of the headers and intake. So yes it will run but I would get a tune.

It will be fine, Ive had my Fast 90 setup on for 6 months now but I am getting ready to change injectors and take it and have the tune messed with for the injectors mainly but the tune for the intake won't hurt.

yeah you don't have to but after I put on a 90/90 combo and logged some data runs with my wideband O2 sensor it was anywhere from 5-15% leaner (getting more air than my LS6 intake) up above 3500 rpms.
