This is quite interesting. I have just had quite a bit of tuning work done on my MINI including a big-bore TB, and whilst it goes like stink at high throttle angles, it does have an annoying flat spot between 2700 - 3500 at part throttle.

When you say 'most' TB's cause dead spots, where are you getting your information from, as I would like to investigate the subject more.

Cheers, Richard
