max safe boost on stock turbo

[2manytoyz]

I know everyone says about 28,i have a 5" exhaust and php tunes,k&n filter(i know i know)Truck is a 00 auto truck.Not looking to break speed records but the thing will overboost on the 65dd setting on the chip,lol
I have a ww stock turbo and ebpv deleted.Even defueling ive seen 32-33 lbs just playing around in lower gears. Im going to do the map sensor mod but what should i restrict my turbo to? I have a 35 lb gauge im going to run,thing 30-32 will suffice? I plan on towing with this truck,so i really need the wastegate to work too,currently its unplugged. Should i run a boost controller on the wastegate AND map? Whats the consensious on the best way to do this?
I dont plan on doing any more mods to the truck-so where should i set it?

I wouldn't even let mine hit 30psi at that point you're impacting the life of your turbo. And anything over 24psi on the stocker it starts becoming inefficient as you're just heating the air.
