My inbox has been flooded with inquiries about the cars and parts etc, and I'm sorry that I wasn't able to reply in time.
The car is very much alive and kicking, spitting out flames at the exhaust on 3rd gear when I pedal it on the highway.
The boost setting of 1.6 bar has proven more than adequate for daily driving for now, and while I have no complaints on the power delivery but now I am starting to get used to it.
So this means either I have to learn to be contented with what I have, or plan for more upgrades.
