will this also work if your a 2.2 with a 2.4 intake manifold swap??? if so are we going to need a tune???

NO tuning required? Yeah right. This would change air flow a lot I would think.

Change in airflow is compensated for by the MAF. That is why you don't need to change the PCM when you drive on a cold day, in the mountains, or after installing mods like headers or ported heads.

I don't know. The change in TB size in a 2.2 may require PCM tuning as the calculated flow vs. TPS will start to be off by too much.

i think there are a few 2.2's running the 2.4 manifold and TB. You may want to ask them, i know there are some drastic changes when you put the bigger LS4 Tb on the LSJ, this may or may not be the same case with the 2.2/LSJ TB swap.

Are you guys working on an intake manifold for 2.4's?
