Tune needed for FAST90?

Is a dyno tune needed for a simple FAST90 swap even if the car was tuned for a stock LS6 intake?

no but the tune needs to be adjusted. your AFR will be way off to the lean side. btw, have it ported, it helps to avoid any loss in low end tq. pretty much eliminates it.

and it maximizes the potential of the FAST...just more sick power

some people seem to have issues with the idle after the install as well.

so it will probably need a retune...at least a touch up.

YES. You will need your tune worked on.
