Scangauge 2 or Bully Dog GT

[asgard]

I have recently been getting a check engine light and while I would like to check this out and clear it i would also like some additional information. I am looking for advice by way of actual user reviews as to which one is best and why.
appreciate there is a reasonable cost difference but I am open to advice.

Also can these be changed from car to car without modification, I fell the scangauge can but unsure as to the specific nature of the Bully Dog. They also advertise an additional pyro probe - is this needed?

thanks for your help

If you go to:
http://www.cleanmpg.com/forums/showthre ... ght=xgauge
it gives some pointers how to program the X-Gauges on the SG2. If you join the forum, they have it for $134.95.. It may be slightly less elsewhere, but I am hoping for support when needed. Among the things I want are (hope these will be supported by Nissan):
Trans temp
Trans slip
Air to fuel ratio
O2 sensor readout

Mine should be here in about a week

I too am intrested in this. I'm looking to get both the triple Dog GT and the RFI kit as well.
