help

i have a sts turbo on my chevy silverado 2005 5.3 v8 i have upgraded injectors headers thats about it right now lol but i was wondering how much boost my motor can handle i have a 10 spring on there right now im at 5-7psi but i want to boost up too 10-15psi... my truck is still slow to me at 5-7psi but i also have 22's on it i dont know if that maybe wieghing me down but just let me know what yall think

those wheels are weighn u down and yeah u can hold more boost i think ducky is running 12 or 13 on a sts

You should be just fine at 10lbs. I am at 12 over here and no problems yet

10 lb spring but only 5-7 psi? Something isn't spooling up correctly...

Okay...I KNOW I've posted this twice already...but here goes again. If you have the stock 60E (I don't know because that info is not visible) it will not hold 10 or more psi. :twocents: but it's been proven over and over again...
