Considering a pulley change. 2011+

[DamanC]

So I'm considering going down to a 3.48 pulley size from 3.6 on my Vortech kit. I already have a KB fuel pump booster 47# injectors and am tuned by Lund, the motor is stock otherwise . I currently max our at 7.5-8.5 lbs of boost. What other mods should I do and how much more power can I expect?

I'm thinking the same thing, I have a 3.80 and would like to try a 3.60 to beat my 10.66 pass
