THANKS,,,,SCOTT_OVERMANN@TRIHEALTH.COM

 

i'm going to say it depends on the ammount of boost you will be running.... when it comes to foced induction, thats were the learning cure went the other way for me... lol!!!

if i had to pull a number off the top of my head i will say 30lb.......

this way you know if you decide to run more boost you wont have to buy bigger injectors.....

again, don't qoute me on that......

be sure to get a custom chip so you know the a/f ratio is right on, belive me, you don't want to go lean with sc.......


later
