Hmm... first post in a very long time.. I've been enjoying the car too much ;)
I've doing some well deserved and long overdue maintanence and found the following:

This is on a TB48 where I had a new engine installed 13 months ago, noting that the 'install' was simply a drive-in-drive-out service and I had the car tuned at an LPG specialist after the event.
I this is the powervalve, not EGR as I guessed earlier.
The question is, is the a good mod to leave on the petrol engine ?
Could this be contributing to really lousy fuel economy even for a tb48?
Should I remove it ?
If I do am I up for a retune ?
Although I suspect most of my economy issues may come down to the black MAF sensor, it was that bad I couldn't see the metal strip at first. Clean now so time will tell if that makes a difference.
Cheers
Jason.
