Anti lag Any toasted valves and turbo's gen Imo theres no point on a road going car,running autronic(or similar)you can set the antilag to a bare minimum where it'll work more as a sound and light show than actually keeping the turbo spooled up.
If you must all you need to do is have the igntion retard so the flame front escapes while the ex valve is open,add a wee bit of fuel(possible run a 5th or cold start)and hey presto one melted turbo i mean antilag
