My Trip to TDI
On Monday this week I spent the day over at TDI in Thurrock while my car was tested on their dyno and then had a new exhaust manifold fitted.
I recently got a Berk ceramic coated manifold from Berk Technologies in the US and not only wanted it fitted but also wanted to test its performance because I |
Hubs are moer accurate than RRs because they are removing more variables (Rolling radius, wheel size, tyre size, camber, toe etc etc) that wheels will introduce :)
Still, I would argue that the shape of the curve is far more important than the number you get :) |

Exactly and the shape was similar to previous although I think TDI do the test over a longer period of time.
