Getting dynoflash custom tuned soon and want to get everything sorted out before the tune
Current Mods:
Works Catback

Works HFC (how much HP am I losing with my setup vs testpipe)

HELIX DOWNPIPE VERSION 2 Ceramic coated

AMS Cone Intake (seems to make hp go down (now) but maby not after tune? Also it just sits freely no bracket?) Should I stick with stock? or get the Buschur Mass Air Pipe & Filter Kit or just the Buschur Filter any hp diff? or just use the ams one i own?

255 Fuel Pump (installing before tune)

Hallman MBC

anything else that would be easy that would not cost me a lot of money and give me HP?

Lower Intercooler Pipe?
O2 housing (hard to install?)
or
Save money for new cluch

 

the 02 housing would be a good mod for not a lot of money. If you installed the exhaust and dp, then i dont think that the 02 housing should be all that hard to install for you. there are a couple right ups on this forum about it too.

other then that, save up some money for a clutch because after the tune, you will probably be racing a little more then before.
