Hi, After thinking the car was holding back a bit in "kick down" I have fitted a Boost pressure gauge. However on full throttle it reads 22 psi then drops to around 15 psi. Now in old RS Turbo money which was the last time I messed with gauges etc 22psi was mind blowing, ( and head blowing ) Yet it still feels its holding back. It was serviced a few months ago, oil/fuel/ and as much as I dislike them I even ran a fuel additive through it.
Any ideas , or was the 2.2 cdi a bit lame?
Cheers:wallbash:

The 22psi is just a bit of overboost, the 15psi is the correct figure.

A 220 isn't a ball of fire, but if it's jerky at all then the EGR valve might be sticking open a bit.
