Ok I think I'm pretty near the top tune on Hsn but will try to get abit more out of it and maybe a longer run, will get some more speed runs after a tune and see what I get, also I'll get a small spur and see what difference it makes.
im sure there are people out there with tmaxx's who have tested the stock speed and gearing anyone?
thanks and I'll try get the maxx rolling abit faster
