Default Next step HP gain help???

Got a 05 GT convertible, 4.6, 3 valve, 5 speed.
So far we installed Steeda UDP's, Steeda CAI, Magnaflow high flow cats and a SCT custom tune. + a Hurst competition plus short throw shifter.
I'm looking for the next step and bang for the buck for HP increase.
Do I get headers, delete plates, bigger throttle body, cams or what.
Not quite ready for the high priced supercharge YET.
What do the experts recommend?
Any and all suggestions would be appreciated.
Thanks in advance

It really depends on what you're looking for. No reason for the throttle body unless you've got cams, headers and spin the motor over 6500rpms. The delete plates to me are more of a safety mod and also help out when you have headers and cams since it will let them flow better.

I would get a nice 1-piece aluminum driveshaft first, then long tubes, then cams & delete plates together if I were to pick an order.

Cam's with LT's would probably be the best bang. Afternarket TB's are useless unless you're HEAVILY modded so nix the TB thought. UDP's, electric waterpump, aluminum DS... Just a few thoughts off the top of my head.

If I hadn't been made to get rid of mine, the mods I kept hearing over and over from all the experts were CMCV Delete, UDPs, and possibly new headers/exhaust components.

I'm a fan of the stock cams for drivability and smog issues.

My vote is for long tubes and/or delete plates.

If you decide on delete plates, I have some for sale.

PM me

Long tubes will work. I have CMCV and bigger TB and I don't have cams or headers at this point and I felt a difference.

if you want the best "bang" get gears. while there is no hp increase it will "feel" like more hp than any other "bolt on." drive shaft would be nice, headers if you can go lt if not i wouldn't waste my money on shorties. don't forget after you have more of these go fast mods you will want something to hold it there, such as lcas and other suspension upgrades
