For the long LSN your settings sound about right. Maybe a little lean on the HSN, but that depends on pipe, how run in engine is etc, etc.
I run a 7.5 mm blue Go restrictor on my stock 7 Port Turbo and it goes great. I haven't done any side by side direct comparison with other motors (only going down the straight at my local track when racing, and the 7 Port comfortably holds it's own against other more expensive motors).
Running 0801 pipe, HSN 1/2 to 3/4 in from flush depending on conditions, LSN 2 1/2 to 2 3/4 once again dependant on conditions of the day.
1. I'm running Hong Nor 053 pipe.
2. I have new long needle.
I think I will try 8 mm insert.
