also have the motec, but the m4 is getting a bit dated, the dos program to tune it is fairly simple to use but timing consuming,i finding it quite interesting,being able to tweak tuner map's that are set to rich for economy etc.also the fact alot of other aspect can be tailered boost/nos map's/water injection to your own need's.and the fact if i sell the pulsar i''ll be able reomve it and keep it for my next car.but i think i may have reached the limit of my mapping skill's, need map it with a map senser and throttle bodies, is quite hard as you have to use map/efficincy and tps/rpm as load bascially having two map's for fueling to get the best out of it.
