The main difference, w/the V-6 Syclone engine is that it is fuel injected (more even fuel distribution) & has a computer & will control knocking/detonation.

Your A/F ratios cylinder to cylinder will be off.

I would not recommend you going over the boost you were already seeing.
I'll chime in later & type more.

BTW, how about some more pics of your downpipe & pipeing to the carb, bov, etc.
