Hi guys so far I have added a K&N CAI with a Airaid TBS and a Diablo Tunner at 93oct with CAI. Im planing to add a 180 T stat and maybe the Catch Can. Is there a tunner modification that i should add or remove or another mod I should consider? Thanks guys for any help.

How about a cat-back exhaust of some kind? Not only would you get a little more performance, your Challenger will sound better.

Another simple mod is a bigger throttle body, 85, 87, or 90 mm. You can get 85 or 87 mm for less as a ported version of the stock throttle body (plus it looks stock for dealer and/or smog inspections).

At that point, you should consider getting a custom dyno tune. There are plenty of vendors that will send you a tune via email and using your Diablo tuner to data log. You can also go to an dyno tech shop in your area that knows the modern HEMI engines. After I did the mods similar to you, plus the TB and exhaust, I got a custom dyno tune and went from 386 to 402 rwhp. If you live in the SF Bay Area, I can recommend the shop I went if you'd like (PM me).

Any other ways you'd like us to spend your money, let us know. I'm sure tons of people are willing to help with that. ;)

There are plenty of modification you can do. It all depends upon your budget.

headers and cats for sure.. Id wait on the custom tune though, cause your gonna add more stuff and just have to retune it again.

Wow guys thanks a lot. I'll think about the exhaust and the TB.402 wrhp sounds incredible. I'll just take my time now during the summer because of the summer gas prices. Again thanks
