Re: Help with more horse !
Yes Flyinryan is 1000% say you put a cai your car and the treat diff goes no relation. No reason to void warranty. Just a simple example.
Best bang for buck mod is a turner, diablo or sct, since you have a Hemi. This will improve your performance, mpg, shift points etc. the turner will hold your stock tune so you can immediately put the stick tune back on before going back to the dealer. I heard a power wire is good for the Hemi but a Hemi guy will have to add info on that. Flyinryan does an outstanding job on porting and polishing your tb which has great results but that will be altering oem parts but a great mod for the price. Dollar for dollar best mod and you can just buy a tb from him and just keep your original.
Other then that just stick with basic bolt on mods such as a cai. Minimal gains but you will be able to switch them out quickly if you eer have to go to the dealer if that's what your worried about. I have never heard of a dealer saying anything about a cai though. Hope this helps Alittle good luck
