Yes. Tune was f'd in the A, which is why I blew a piston. Those were base line figures.
CobraSS, Secondary - 80 / Primary - 94
I think you're supposed to keep them within a difference of 10, but at this point I might tell that rule of thumb to suck it.
Today I replaced the stock (33?) high speed air bleeds with some 28s, huuuge difference. Check out the graph, close to 12:1 under boost (only opened it up to about 5 lbs to be safe).
The rpm is not accurate (black line) but at least you can tell when I opened it up.
Tomorrow I plan to drop the primaries, prob down in the 76 range.
