85mm to 82mm pulley

[robwlf]

i searched a few times seen alot of mixed stuff..
so my buddy has a 82mm pulley he will give me in place of my 85mm if i can use it which i can im thinking... just wondering do i need to tune it for the pulley or will the roush tune thats on there be good with the increase..i know its like a 1 or 2 lb increase in boost,and i know the current belt will be good ... just wondering before i say yes and it messes something up if i dont tune it .

its a tvs system

thanks in advance

Have lund revise the tune. Put it on and data log. A 2lb increase in boost requires more fuel!
