21.3 psi - but i've yet to actually hit that high - that is where the EBC is set to stop things going boom :P

the highest its hit is 19.8 psi - the PFC hand controller is full of fun information ;-)

I have four settings on the ebc
1 = 10psi nanna mode, then
2 = 14psi , which is pretty much exactly where the car was before the tune,
3 = 16psi
4 = 21.3psi

i really doubt ill take it off 4, cept when someone else is driving perhaps. its well hidden so they wouldnt know the difference hehehe.

and as for track weapon, that has less to do with engine power - more to do with suspension, which needs work so ill probably be slower now as i over shoot corners ;-)

in any case my tune was surprisingly cheap. JUST DO IT! (tm)
