I have posted a previous thread on a utec ecu vs. a aam ecu reflash and ended up with the utec ecu but also was wondering if anyone had any idea whats the highest boost i can put on a stock block without blowing it? I putting the greddy twin kit but i want the most power but also run it safe and reliable. Any thoughts??? Thanks in advance.

lol jk about 8 im guessing, but it mostly depends on how good your tune is. Ivs heard that the greddy tt is not too safe for stock blocks. If i vere you id go for a vortech sc or the turbonetics single turbo kit.

 

boost is not an indicator of power. you can put ~400 ft-lbs of torque on the stock block regardless of boost.
