Only driven about 3 miles tops with it, but didn't notice any difference.
Fired it up and let it idle to check it was cool. The R-vit was reading as normal so gently drove out the carpark, then gave it some stick on the backroads here. Boost was peaking at normal levels so no leaks hopefully. Car feels the same basically.
Except the big smile on my face.
No prizes sharon. Except a free woosh if I ever pass you.
