AFR is 11.3:1 under boost, What would you suggest? I log all my rides and check tune after each, motor is fully built low compression. I ran it last year at 19LBS, with 4 degrees pulled....this year i went back to 30 degrees at 15LBS.
My old busa setup...current bike is setup the same except it has d200 digital dash, CP pistons and extended swingarm..
*Velocity stage two turbo kit, with Hks blow off valve. Replace the oil drain flange that came with the turbo with a after market billet *drain flange..i also run a full 4qrts...
I'm very happy with my turbo Gen1, making about 350-360 hp, runs great and corners great, to me, i have no complaints, but i would entertain the possibility of purchasing the Gen3 if suzuki step there game up, always room for another busa in the garage.
