I have an ep91 glanza v it runs spot on it low boost but when I put it in high boost and go threw the hole rev range it feels like it hits the limiter at 4. Thousand rmp the if I let it carry on again to 5 thou and it jolts forward and the eml comes on and stays on for a bit while im driving normally I have done the blink test and it blinked 34 the map sensor but I would've thought it would have done the same in low boost any ideas or would you say that's right any help would be much appreciated cheers shakes
