I am going to be running 14 psi, on the stock turbo w/ an XS engineering FMIC and 255 Walrbo fuel pump. Do I need any fuel controller? It doesnt seem right that I can double the boost on the stock ecu. Will I be ok w/ no fuel controller until I need new injectors?

you'll be fine at 14psi. I'm currently running 14psi and have had no issues

nah 14psi is fine...anything over 15psi is kinda pushin it as the stock turbos on the SR arent really made to push that much air without threat of damage to the turbo...if your boost controller supports its run 14psi low to mid and 10psi at top range (where the boost will drop down after about 5-6k rpms) i did that on my redtop for a while and its got alot of umph for drag and drift
