Hi,
I have some hesitastions problems with my Fiat Punto T-Jet (and with me some other on the dutch forum). The car seems to hesitate a little bit when pulling from 3th, 4th and even 5th gear. Feels like very little hesitations one after another. I decided to make a log of it, which i've added to this post. In low RPM actual boost is way lower then desired boost, but at the midrange it sometimes also a bit more then 0,1 bar difference in 4th and more then 0,2 in 3th, which is too much in my opinion. Car is bone stock and because of the hesitation i've replaced the spark plugs (to no avail). Don't know where else to look.
Hope you can help me out.
