You'll find a hard time getting ahold of people with that swap anywhere, it's not very common :P I'm no expert, but let's try to get out some more information

Did it run fine at 7PSI with the stock exhaust? Basically, when did you first run into this problem?

By "no idle," do you mean it stalls out unless you give it gas?

Essentially, you will want to get it running OK at the stock 7PSI before you try to increase the boost.

Check for boost leaks and properly functioning MAF
