I plan on getting low comp. pistions, turbo cam and afew other goodies, my question is: I now run 9 pounds of boost if I wanted to turn the boost up to say 15 pounds of boost would I need to have an A and B map? Would I also need a boost fuel dependent regulator?

Whats your present setup?
Do you have a turbo map sensor?
If not then I would assume that your setup is already now depending on a rising rate fuel pressure regulator.
I would not recommend boost pressures higher then 11 psi - based on what I read from other members with such a setup.

You can run 15psi of boost, but you'll need a map for it. You have to remember that the 15psi will be quite a bit, so it'll run much hotter. You don't want to stay WOT for any long periods of time. I would also stud the cases and heads(heads need machined for 12mm) and replace the rods. If you don't map it(more fuel) you'll melt a piston quickly!

Rick,

make an air to air intercooler already to help alleviate that issue. I bet you could sell quite a few of them!
