[That's okay with me -- I like "feeling" something, which is probably why my favorite part of driving is working the clutch and double-clutching into first...]

I don't think that you are going to get a gear change - as in the actual feeling of the shift coupled with a smooth transition of power from the engine and an appropriate feeling of acceleration or deceleration of the vehicle like you get in your Corolla when you make the sort of DIY solution that you are suggesting.

[...so are you saying that the double-clutching in my Corolla is not the same as double-clutching a TN? I expect that. The Corolla is too lax on me when my double-clutch is slightly off.]

Usually these types of solution are OK / great / excellent to the person who did it because they "did it" - only they are likely not to be critical about it - only they are happy to double de-clutch or ease off on the accelerator "when it does that" etc. Now there's nothing wrong with this kind of DIY modification - Renault do it all the time - but then they sell stuff to people who will put up with their **** because it is discounted and they get the feeling that they've had a good deal...

[If you love French cars so much, why do you have a German one? ]

...sorry for the French car rant (!) - Basically be realistic with what you can achieve. Do some sums to see how you think the engine will cope in all gears not just the top end calculation.

[...working on that right now.]
