Jack's comments about high engine load during launch, sounds a little like the antilag feature that Cobb/Ecutek have. You engage it on a constant throttle (like say 10% like on the freeway), immediately you see the boost gauge stand to attention, and if you have an aftermarket intake you hear the turbos spool up. Floor it and the engine responds with no lag, almost like a manual car when you pop the clutch. I should ask my tuner if he can do this

[@The.Garage.Studio]

Kinda the best of both worlds. No turbo lag;... and minimal shock to the drivetrane.

[@KevinSan88]

@@The.Garage.Studio I believe the way it works, is that retarding the ignition a lot means that there is incomplete combustion, and a lot of unburnt fuel goes straight into the mouth of the turbo. The fuel hits the hot turbo blades and there's a little explosion which spins them up.

[@The.Garage.Studio]

Hm.. sorry about that. Will keep that in mind.
