mine isn't 85 anymore

replaced a kinked hose and ran the boost signal from the plenum instead of turbo compressor

now it revs to 6000 and holds 9psi right through

was maxing out and blowing lots of fuel smoke by 4500rpm before

drives awesome now (wish i could do the dyno and phillip island again), i think the big change was the kinked hose, i cant see the different boost signal making that much difference, i dont know what the hose does... see pic... it goes from inlet pipes to a large diaphram type unit and somewhere else under the inlet
