I think I will be happy with stage 1 for now and take my time if I want more. I already have the TBE which I assume will make a difference at stage 1 also?
....Yes, the TBE component should add some significant power when you go Stage 1.
We wait for the usual enthusiastic whoopee's etc posted after you have had your first drive on Stage 1
The difference between Revo Stage 1 and 2 is far more subtle - Strong, but subtle.
I did that, then told EVERYONE I've ever met about it as well.
