quick boost question
 

hey guys, sorry for the newb question but here it goes..

Since my procharger will be going on soon I was wondering which pully to use. I have the 3.4 and the 4.0. Is it better to use the smaller pully and tune it more aggressive or use the bigger pully and get a more conservative tune?, either way making around the same power. Thanks.

I think you might have confused yourself there but I know what you meant. Smaller pulley and conservative tune is the way to go, so go with the 3.4 which should give you 9-10psi. On a conservative tune you shooing have much of a problem getting to 450whp.

yea my bad wrote that backwards
