Tuning twins

Ok folks. I'm about to get my gauges installed - what pressure should I be aiming for between the turbos vs overall and what is the best method of tuning to get there? Thanks!

Ideally you want the boost in the cold pipe to be 1/2 of boost in the intake manifold. I also hope you have a drive pressure gauge as they are critically important with twins. You want to drive a drive pressure ratio of 1 to 1 throughout the range ideally. In my case drive pressure runs 1 to 3 PSI over boost, which is perfectly acceptable to me. You adjust the boost in the cold pipe by changing the wastegate settings. Every setup is slightly different so the particulars will depend on your exact setup. Enjoy your twins! I know I love mine...
