would have a spontaneous question about a so-called "power boost valve" from atb-tuning.de.
The following: This petrol pressure regulator is said to produce better flow from the speed cellar, up to 8% more top performance and elimination of power holes. Also slight improvements in consumption are praised and goods is incl. Report and a price of well below 200 euros. Good instructions for use, as well as easy installation, are also mentioned, which was positively confirmed by various customers in reviews.
However, it was also all about "smaller" cars...
With the K&N filter the part is supposed to harmonize super (same we have already installed in our ́89er) and slightly reinforced response and a little bit more bite even below almost 5000/min does certainly good due to the long-translated automatic and the high weight also a spin-like 250hp sedan
.Question would be: who already has experience with this petrol pressure regulator and how worthwhile would the investment be?
Thank you in advance.
