I like the Xenium and the X2 series chips the best. But I think those 2 chips are damn near identical in features.
Hi ok firstly sorry but i just cant resist !!! *cough*cough* does a nod chip sit in your cars rear window by any chance and nods as you brake in regards to a MOD chip like "daPhoenix" states xenium is a good chip, but depending on your fitting skills either of those chips you mention will do all you require Regards
