How do I do this?

So I understand you need a turbo and I have one but I want to know how to do this in This video

Anti lag. I don't have much personal experience, but I think for most applications it's a setting in your tuner software and a little extra fuel plumbing. Rally cars use it a lot to hold boost off throttle, not the best thing for your turbo or exhaust though, as it detonates fuel after the turbo to keep the boost up.

I think Im remembering that description correctly.

And how would one make something an anti lag in the most haggard way possible

Following with interest.

That is a heavenly sound!

Yeah this is awesome but I would suggest at least get a pro involved. Maybe you guys can work together (50/50) on it. Especially if this is your first time. Man please keep us updated on this :)

just me, but that sounds more like a 2 step system rather than anti-lag...
