Hi, I have just imported a glanza which,as far as I know, is mildly modified with HKS parts. I am very impressed with the performance but when revved to over six thousand the boost reaches one bar and a light comes on the dash.I am led to believe this is fuel cut although the car does not jerk or judder.I have looked at the ecu and it appears to be standard,there is no boost controller and the boost solenoid looks standard.Also cant see a FCD.So how has the boost been turned up? Will be selling it soon and dont want to sell it without knowing if the light is anything to worry about. Any advice
