So it is best to know what your A/F ratio is before starting. If your A/F is at or below 13 its good to go. Otherwise the best results can be made with a tune to increase the fuel flow rate to compensate for the additional air flow.
I hope this answers your question.

Hi guys,
On the 287 engine, for area under the curve, the MREV2 actually makes a little bit more than even the spacer. But the difference is pretty small.
The spacer makes about 1-2 HP more at the peak, but the MREV2 makes 1-2 more TQ with a little more midrange.
You could do either one and get pretty much the same results, they both predominantly add top end. There is a little bit of a trade off between them though.
1) the spacer has very good stealth and a little more bang for the buck.
2) the MREV2 has 100% stealth and a little more area under the curve.
And no matter what you do, if you have a REVUP engine, do both!

So on a 287 what could we expect in gains with Mrev2 + Spacer?
