PSI Question I have a used 4 PSI ATI on order and I was wondering if I should up the boost and change pulley, the fuel injectors, and get a tune, or if I should just install what I have. What PSI do you guys consider safe on an LS1 with stock internals and compression?

You can put the 3.6" pulley on it which will get you around 7-8 psi......you will probably see 5 or 6 due to the LT headers.......
But I would upgrade to 42.5LB injectors if you do that at the least and make sure you get a good tune.......
