Yes, l have had the car about 5 years and l dont run it very hard. However every now and then l give it a little bit.
As for the problem with boosting, l am not sure what is causing it at times. l've had full boost and it goes pretty hard but for most of time it boosts a little. l can hear the boost and see the guage show boost, but there is a lack of power or may another way of looking at it is the turbo is fully boosting but there is something stopping the the power. Could the dizzy have a intermiten fault which is a motor problem, not turbo problem? Or something like the knock sensor? l just want to fix it but do not know where to start (I am not a machanic.)
Thanks MJ
