It's because my tubes were all replaced with pattern parts (pricey enough at £180 for the set!) instead of genuine by previous so the inlet pipe deforms and the boost pipes are well soft to the touch, think oil spray on them has degraded the rubber badly. If I spot some good genuine ones they'll go on instead.
Makes a weird warbling followed by flat spot when it does do it though
