I been posting allot latey on these sts kits. But I had one more question. This summer I only plan to run maybee 5psi the most on my stock and 7psi when one of those cobras or vettes pull next to me. Running that type of boost will I need to upgrade the stock injectors and fuel pump. I just wanted to run low boost on my stock engine till it blows and then run max boost with upgraded injectors,fuel pump. 5PSI ON a stock engine should last long with a good tune right??? Only internal mod is the hot cam. Anyone here ran the sts kit on there stock engine - if so how many miles did you get out of it- Mike
