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.
I was playing with the settings today. The engine performed well (not optimal) when HSN was 3/4 turn from flush and LSN 2 turns from flush.
I realized that when it was only for about 1 minut left of fuel in tank, engine gone insane in positive way (screming when accelerating and top speed was excelent).
Then I tried to lean down HSN and LSN when the fuel tank was full and no positive effect .
What to do?
thanks,
