I would have agree with Bank on this one. Most would not trade a boosted motor with a stronger bottom end unless something was wrong. Personally I went with a zzp kit. I installed their stage 2 kit and trifecta tune a couple weeks ago on my 2.2 and have a grin every time I drive it. As for the bottom end, the parts are available to build it up for more boost, and for the most part a 2.4 would be slightly easier as zzp has a base tune for a 2.4 to run on until OP could get to a hp tuner guy or trifecta.
