Basic with regard to loading pressure!

Hello! So after we all had the workshop “Ladedruckanzeige” in Osnabrück many weeks ago, I set myself up again to optimize the installation! The background was on the one hand the hint from N.M.E, that with him in the T-piece on the petrol pressure regulator was a small hole (I also had!) and the statement from T.Wimmer, who said to me during a test drive of my TT ́s: “With the construction of the LD something is wrong with you!” The explanation was actually obvious, because with the Ins Trumenten supplied hose is too soft and pulls together. This means that the car can also run too thin (less pressure on the petrol pressure regulator). So I have now replaced the T-piece with a new one, the restrector of the original sits in the hose before, and the hose itself is replaced by a fuel or vacuum hose. Has also worked fine! But now to my question, the displayed LD has changed now however: at idle -0.8 bar (v orher -0.7 bar) in thrust operation -1.0 bar (previously -0.9 bar) and in the overboost approx. 1.1 bar (previously 1.1 -1.2 bar) Are the values for a clipped 180 hp AJQ engine in order or not? Do I feel that I would lack some power, but can also be due to the subjective impression. What do you say?
