that is propably true... but totally against the rules..
on a turbospecifig EFI like autronic there is a feature called ALS, anti lag system.. that retards timimg and increases fuel delivery... this what gives the tell tale POP's in the exhaust... his "exploding fuel-air mix" in the exhaust manifold keeps RPM's on the turbine when throttle is lifted..
id just get a NOS, wet system that comes on at WOT and kill it with a boost switch... that way all you have to do is install the kit, and engineer the controlls (buy a micro-switch and one pressire switch)
