is there a difference in gsr obd1's and obd2's basically just want to know about performance wise.i already now they have different sensors and ****, and the same amount of hp #'s (not including the 92-93 b17 gsr) is obd1 faster in any way than obd2?
actually now that i think about it what does obd mean.

I see no performance difference if everything is running right.
They both have the Pro's and COn's

 

pros and cons?? what are they in each?
