Pulley swap question

How much more boost will I make with a 3.4 pulley rather than the stock pulley on my 98 gtp? I know every car is different but a ballpark would be nice and will it be a definite difference?

Any more info on your mods? Weather and elevation will play a huge role as well. I see you're in Washington, if you're at high elevation you might get away with a smaller pulley even if you're stock.

Doesn't sound like the mods required to drop down to a 3.4. You'll end up being slower than stock (unless you're way up in the mountains) and possibly damaging something. Grab some headers and a custom tune and you should be able to use a 3.4.
 


and more importantly who's doing the tune or what tune do you have? and I sure hope you have something to scan w/ like a aeroforce.
