What effect would -mild turbo bike timing
For a 7 PSI turbo'd bike, ATP, Harry said that stock timing is ok for his kit at stage 1... mine is setup stage 1.
I have the timing -6.
Do you think changing to OEM timing would make a significant/noticably tellable difference in performance?

Yes, a very noticable increase in power, as long as it doesn't detonate.
probably 15 RWHP increase

you are running Muzzy timing plate?
Try moving it back a bit at at time, and listen very close , especially under load , lower rpm and at max boost... be careful!
If you hear or feel any difference, that may be detonation, get out of it immediateltly and pull back on the timing.
Don't forget, fuel is seasonal, and usually worse in colder seasons...

i can tell you -8 degrees is a killer on power .. i run -2 with 10lbs on avgas ...sometimes it mixed with pump gas 50/50
also had a 40hp loss on the dyno with -6 with 14lbs ..all we did was plug and unplug the EFIR
