So I went to get my car tuned put down 525rwhp previous setup put down 470 to the wheels. So when it went to get tuned with 525 and only 6lbs of boost? I'm thinking those numbers are pretty low. So the tuner said it was because I'm running big flowing heads a large cam and lomg tube should the car have put down more power then that? Car also ran like **** he said it was because my car was an auto and o2 sensors were not reading, I put my scanner on and they read fine. So I looked at my bypass valves and they were stuck open even on acceleration I know that would definitely effect my boost and number gains how does this cam sound to you on a
98 camaro ls1 383

If your bypass valve is open it won't make any boost at all. When the bypass valve sees near zero vacuum the valve will close, when then directs the boost into the engine. Bob

I would also run 100% methanol, as a water mixture can put out the flame. Bob

I think the problem was the the vacuum was plumbed into the break boost vs the intake. It would close at all. When I hooked it to the intake port it closes when I hit the gas. And ok Th the methanol I'll look into running Stai ght meth
