I'd say stage 1.5. LOL Some things on the stage 2 was put onto mine. ATP turbo kit complete with B.O.V., GT30R turbo, dump pipe, MTC multi stage lock up clutch, dual cooling fans, Ohlin forks, Ohlin shock, Ohlin steering damper, LM2 A.F.R. meter & data logger, Carrozzeria wheels, SS braided brake and clutch lines, ZX-10 front fender, rear hugger...
AFR at full boost is pretty rich. I want to say it drops down to 10.5 - 11.0 to 1. At least that's what I see on the readout when I get on it. I run 91 octane pump gas most the time. I try to mix some 100 Octane race gas available at my local 76 station, so I'd say the tank usually has half race gas, making it around 95 octane.
Life's too short to deal with assholes.
