As title guys - I've spent the last couple of hours searching through all of the threads on here, and seem to be no closer to deciding which one would be suitable for what I'm after...
All i really want is one that will whow me when the car is running lean, is reliable, and preferably has an alarm...(if any of them do - I think the tech edge jobbie does?)
It needs to fit into a 52mm a pillar mount...

So, what fits the bill....? I'm liking the look of the new Stack...... BUT i've not read any reports on this, so I guess the Tech-edge wins ? - but can it do all of the above... - or not?

I've also read that the innovates are good....BUT the wiring needs to be perfect....The main benefit of these is the sensor will essentially tell you when its sligthly past its peak?...

Any comments..?
