Does anyone know if you have a nelson tuner programmed at 7lbs and you get a smaller pulley for the charger will it be safe to run the truck or do i have to send the tuner out for updates due to the fact that i will boost more?

what is your exact set up? if you dont have an intercooler i wouldn't go any higher even with a custom tune unless you run some good gas or meth.

i think the radix(intercooled) guys are running more than 7psi on pump. your tune would "probably" still be ok but it is hard to beat a local dyno/street tune.
