If your turbo isn’t at full boost you’re not getting full performance, so you know what you need? Anti-lag! There’s a few variations on this, from the common stuff that works from a standing start only, to ‘rolling anti-lag’ which people use for roll racing, to proper rally-style anti-lag which can give you full boost literally all the time. The basic idea is the same; to get your car producing boost when normally it wouldn’t be, and therefore allowing you to accelerate like a rocket the instant you open the throttle.
All forms of anti-lag can potentially shorten the life of certain engine parts due to their aggressive nature and increased heat build-up, and they all make a lot of noise too. But it’s so effective that it’s considered vital to be competitive in most motorsports involving turbocharged cars these days.
