Default what size pulley should I go to next?

I am currently running a 3.4 with a CAI. Also, a 180 stat. I currently have HP Tuners so I can tune my computer. I wanted to know what is the next smaller pulley and if I am going to have to change my injectors?

Thanks

you will need rockers or a cam with stiffer valve springs and OR to go any lower pulley-wise. If you slap a smaller pulley on there now you will see massive KR and boost stack.

Agreed, dont think about a 3.2 (safely) until you have headers and a cam. you wont need to change injectors until you get down to the 3.0 pulley size.

Your stock lifters are fine up to about .530 valve lift (stock cam with 1.9 rockers is .490)
