i have a 07 ss/sc and was wondering what would be the best modd for gains. its basically stock except for the airbox modd. i just wanna know what would be my best modd for the biggest gain in hp/tq.

 

hahn turbo

 

CAI, header, downpipe, cat back exhaust. Tune....

Get a TVS! hahaha

 

tvs is good too. Not hating. Just depends on how you want to gain that hp.

 

First off we need to know what kind of price range you're looking at spending and then we can put you in the right direction.

 

buy my 42# injectors, get a 3" pulley, and get tuned.

 

how much you want for you injectors.

and also with the smaller pulley what else would i need to buy

 

anything lower than 2.9" and you will need 60lbs injectors and a bigger heat exchanger. But any upgrade to the fuel system and pulley will need a tune. There is a lot of threads about this subject.

Any pulley/injector swap you do though requires a tune as well.

 

my injectors and harness for $105 shipped

You need to rent a pulley puller, and buy a modular pulley kit.
modular pulley and hub costs $100.
puller tool is like 75 or something to rent.
