i used the anti lag for a little bit, untill my car farted out the cat converter
it was just to scary with the egt's (holly hot batman)
i would say 1 second is a very long time for antilag and it should be limited to less than .5 seconds and never use the rally version
just be careful and do not use it in conjunction with traction control (also retards ignition) as this will add to the EGT's off the line
if you are building too much boost use less retard and less added fuel (i would recommenced very little added fuel) and your rpm should be high enough that you are not using a ton of retard or extra fuel i think the key would be as little extra fuel and retard as humanly possible
