How hot does it temp when making best power?
Mine varies according conditions. But generally best when run ard 130C.
Mine runs that amt of HSN and LSN because HSN affects LSN tuning
Try to richen your LSN a full turn and see what happen.
Then lean the HSN. Don't compensate by leaning LSN yet.
When got best HSN setting (best top rpm when on longest straight), then tune LSN.
When got LSN setting, richen HSN by quarter turn, shut off engine, grab a beer, wait till cool, try restarting, no more tuning and drive the car on the track to see wether this work or not.
Idle is easy (i presume this will affect your idle a bit) just screw in idle screw to increase idle, hahahaha...
Check the engine tuning bible on top of nitro off-road thread, read it slowly to fully absord what it means. It helped me
