Apex AVCR Questions!!??

Well I have been offered one of these at a good price but I don't know If I should get it. I have done a search on a few boards and there seems to be a bit of grumbling, more along the lines of programing it etc. I looked at there website BUT I couldn't get on of the pages to load,what sort of things can it do? anything Im liable to use? I know it looks cool but will it help me much? Anyone who have one wanna tell me what there like?
Cheers

i know they have gear specific boost settings and multimode so you can set it up for drag or street and change easily on the move. it has boost, speed, injector duty cycle readouts etc which is pretty cool.

yeah my friend's got one in his car.. there is a noticeable difference with the different settings.. in acceleration mainly..
