I dont think the 2.4 TB does a bunch unless you are cammed, and even then I don't think its much. Peak HP numbers are useless, look under the curve if you wanna see actual improvements.
I'm also thinking about getting a 2.4 throttle body and maifold. There is only one problem i'm not tuned yet but i want to be trifecta tuned my next question is how does it react without a tune?
just with an intake i get 100-150 mi more per tank and it took the lag outta my throttle response so if u add the 2.4l manifold only good things can happen
Manifold will work with the 2.2 tb as long as you have an adapter plate, I can make one if that's the route you go just let me know. Otherwise 2.4 tb and a tune but its not necc worth it for your level of mods
