what should i get 1st?

ECU if you can afford it.

 

custom catback or pulley

 

ECU wouldnt be wise yet... just wait till after sema when more after market stuff comes out

pulley would be nice and cheep too

 

Either or would be good, since you have the cat and sri, maybe the ECU...

 

I myself would go with the pully. Everyone that got it raved about it. The ECU on the other hand had mixed results and besides you dont have to worry about voiding the warranty with the pully, where as splicing and changing the fuel injection rates voids the warranty. That again is my 2 cents. go with the pully its also easier to install lol.

 

I say wait until SEMA is over.

 

pulley......will go well with ur SRI and Catback.

 

^ if tuned properly so will the ECU (sri & exhaust), but the pulley is less expensive

 

True the pulley is cheaper but the ECU gets a better return. You get better gass mileage saving you money and added tq and hp. I have both and feel that the ECU was a better buy. I drive 150 miles a day and it has almost paid for itself.

 

rly, what mpg are u getting? and what brand piggy do u have?
