Yes I do look in
and had a good look through yours and quite a few other threads too.
You guys put a lot of far bigger cars to shame.
Mine has 1 bar springs in the wastegate and just about holds 2bar but you can feel it losing boost as soon as it hits that or just under.
We will go for 1.5bar and do the rest with the boost controller as it's well short of what the engine and turbo should be capable of.
Please let me know how you get on...there's no substitute for other ideas and experiences to help set your own car up.
