upgrades needed

[eastbayindian]

Hey guys Im looking to get more power out of my 07 srt8 charger. So far I have:

Flow master exhaust
mopar intake
Diablo Sport
Custom Tune
180-Temp

What else should I get to get more out of the car without having to dig deep in my pockets. I also want to get an SLP underdrive pully. Thanks

What kind of budget are we talking about? You can always do heads, cam, & a tune.
