82mm on Roush ford TVS blower worth it??

[blubyu]

Hey guys, thinking about getting a tune for my 15 GT with roush TVS unit but was wondering is it worth it to drop a pulley size if I don’t do fuel upgrades at the same time? Or since I’m not planning fuel upgrades at this moment would I be safer by keeping the stock 85mm and just doing a tune, instead of tune and pulley swap together without fuel upgrades? What would you guys do to keep it safe?

I would not drop a pulley size on 47 lb injectors and no booster.

Yep, this here. I dropped down to an 82mm pulley and already had a fuel pump booster which was recommended by Lund. I didn't have to change injectors or plugs to drop down. They were the same plugs and injectors from the stock Roush supercharger Phase 1 kit. There was somewhat of a difference going to 82mm from 85mm, admittedly not earth shattering.
