I have about 150-200 bucks to do another mod(s).any ideas? which of these would be the best performance gain

 

cold air intake will gove u the biggest gain, but after that the throttle body will help u a lot if u have maf

 

anyone

 

go with the fuel pump and the intake spacer. that would help out a lot and you get two things. and two things are better than one

 

take the flows off, and put on magnaflows. im assuming you dont have the stock catback pipes?

 

go with the cold air intake and check the top of the intake to underhood clearance before you buy any intake spacer as the spacer may raise up the intake enough to hit the hood if you're not careful.

 

my vote would be a new cam. not only will it sound better, but it will give you a good amount of power gains (especially with a intake manifold and heads). if not that, save up a little for a new intake manifold

 

cai..won't do squat until you get a bigger maf
