Hi,
Need some help,
Got a Is200 sport with the m62 charger, mini bypass ect, since fitting it runs fine but only when the fuel system is closed loop? it misses less past 4000rpm and will redline fine but stick it up a hill and it starts to bog, no codes coming up and seemed to get better when i removed and cleaned the injectors, also plugs got changed from IK20 to IK22 & coils replaced.
Any help would be appreciated.
Thanks,
Tom
