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

Regarding the shape I've felt that with the intake change it's been more progressive at vtec rather than the big gulp and change that I had with the K&N. The dyno plot shows this quite nicely. Will get it scanned and post it shortly.

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

I still remember the day i got it and it was a pile of shit, but now since I've come to
help/participate mapping cars with my mate and dyno mine i know what a waste it was
Seems they do read accurately.

I lost a tiny bit lower down but gained throughout vtec.
