Hi everyone, new to twinair ownership, and as per the title, on hard acceleration I can hear and feel the boost pressure variating, like it's pulsing in and out, it makes accelerating onto the A11 a bit of an experience, it seems to go just fine, but like I say it's not a smooth boost delivery, is that just a characteristic of the engine, or do I have something wrong. It's a 62 reg with 25k miles. Any help will be greatly received thanks ?? Ash
