Gtech pro which one should I get?
 

I can't decide if I need the extra features of the RR. I don't track my car yet but see DE's in the not too distant future. My main purpose is for tuning and documenting mods.

Will the SS do me, or should I shell out the extra 100 clams for the RR?

As you pointed out it's what your use dictates. I used the SS one for some Yukon engine mods I did and was impressed with the info it gave me (did pre and post runs with it).

The SS was all I would have ever needed when I was thinking of buying one.

You can buy mine. Custom blue LED screen to boot. Let me know if your interested.

ehh, i gave mine away after a few days.
really, you will get tired of it in a few.

boggtown, you have PM.
