Hello ,
I have a problem with my m20b25 phase2 stalls at 5500rpm instead of 6500rpm . I have a fast road 270 camshaft + stainless steel exhaust + kn air filter + high flow fuel pump + ECU Stock . I have already tried another ECU with chip/ other injectors / other spark plugs / another fuel regulator /spring adjustment test maf . I have an external AFR the wealth is good ...
I think maybe the PMH or ICV sensor remains a little open?
I am Belgian my English is not very good.
thanks in advance
