to my knowledge, the haltech has the same options that you have listed...
launch control, anti-lag, flat shiffting.
only comes with a 20psi on board map though, so extrat sensors will be required if going for big boost.
ive got a haltech pp in my 32, and couldnt be happier.
find out which has more support from tuners in your area, no good getting and ecu no one can tune.
oh, when i start and run my car, you wouldnt be able to tell it isnt stock.
if youre down near sydney anytime soon, and my engine is back in, pm me, and ill take you for a run...
good luck with either way you go.
