Custom OS or stock e38?

--------------------------------------------------------------------------------

I have a 2006 Z06 with a e38 PCM. It's twin turbo making 7 PSI, it was tuned by the guy I bought it from. It still has a working MAF. I am have lowered the compression to 9.5 and upgraded all the internals. I want to run about 10-12 PSI. Should I work with the stock OS or should I go with a Custom OS in speed density mode with a 2 bar map. I didn't see a custom os that goes with an e38 PCM in the tutorial. Please point me in the right direction.

Thanks

EVI, there is no need for a custom OS on the E38 to run SD and 2bar, GM designed it as a 2bar system.
You MUST read this tutorial as well -

It covers SD tuning on the E38.

There's also no need for you to start 3 seperate threads on this either.

Sorry, I didn't know what section to put it in.

I found that tutorial and have been reading it thanks for the reply.
1 quick question though, I still need a 2 bar MAP right?

Yes, you do need the 2 bar MAP.
