Good morning!

I've been noticing lately the T5 has been a bit hit and miss on whether or not it boosts properly. It has a 304 map up its arse of which I'm lead to believe it should reach the very end of the white on the standard boost gauge? We're more often than not getting about 5mm from the end, that's what they do as standard is it not? It's just coming up to 100k and I recently read the boost control solenoid becomes a service item at around 100k, could this be the problem?

Ben.
