Default A few paxton questions

I have a 1987 L98 Paxton stage two vette. It has headers, rollers roller rockers, 255 lph in tank, ported intake, 58mm tb. I don't have the water injection unit. My question is how much boost is safe without the water injection on 93 octane? I was thinking about just running 6 lbs.

And if anyone has some paxton parts laying around for sale, just let me know.

6psi shoudl be safe if you have the car tuned properly and are running larger injectors to make sure you are rich enough and have the ability to richen up more if needed.. But make sure your also retarding the timing by a few degrees and get no detonation at any of your rpms..

I have the "Stage two computer" eprom. I do think the injectors are stock, It does have the large billet fuel pressure regulator.
