Gee I don't know if I should be replying to this post!
Like whales, a ride like this is rare to find! (and don't say anything about being almost extinct!)
I get my servicing and tune done at Hyperdrive. But as Rev210 puts it, the dyno results aren't something you can go on.
I spose I just want to better my time of 14.8, and the fact that I've got 3" turbo back etc like other R33s that pull in the high 13s etc makes me wonder what it is that's the prob. (besides the whale factor)
I did have suspension and alignment problems (real bad apparently) and they have all been recently fixed, so I don't know if that would effect times??
