I've just fitted a set of technics hybrids, my car is UK spec in top condition, IK24, FCD, Bleed valve, full decat 3'' pipe, TRD air filter. When I boot her she hits and holds (quite easily) 1.45 bar which is quite worrying (even with the bleed valve completely closed). I dont really understand this.
Another friend has exactly the same problem on his UK spec after fitting hybrids.
I'm taking her to C.W tomorrow to have his SMIC fitted and a closer look at the boosting, may need to have a restrictor ring fitted. I know this is standard practice on the Jspec after BPU, but is this normal on a UK?
Cheers
