I have recently ran into an issue with my acceleration being poor when the boost begins to build. There is no bucking or jarring that takes place just a very noticeable lack of acceleration. I have been running the boost around 1 bar while driving casually on the street. The ignition seems healthy and the plugs are brand new all NGK. Where the engine used to just rip when boost climbs it just seems to stay linear in power as the boost rises. I have done multiple boost leak tests and didn't find any noticeable leaks but the vacuum on the gauge isn't down where it used to be it is a bit off from usual at about 400 mmhg in comparison of 500 mmhg before my boost gauge is a metric greddy so sorry if this makes it harder to crunch the numbers. If anyone has any suggestions i would love to hear them thank you.
