Driving technique
Discussion
Ok, having now fitted Racing reds and SH drop links, the next item to tackle is the drive train shunt.
I took the car to a respected and trusted TVR specialist in Surrey who drove the car and said nothing worn or broken in the drive train. All normal !
He suggested he plug in a fault code reader and adjust the static timing,replace throttle cable, all which may help to drive smoothly.
Now on the way home I noticed that when travelling along in a moving traffic queue, in say 2nd gear at 2000 rpm, when you 'lift off' the big jerk happens.
The only way to avoid this is depress the clutch before lifting off the throttle. Is this what other people have to do ?
No timing or fueling or even throttle cable can effect this surely. Once you lift the throttle, the engine revs drop as expected and correctly so and there is a jerk.
Is this a Phenomenon of rear wheel drive cars I had forgotten about and you just have to 'drive around it' ?

It's deninately a setup problem with timing or fuel, my 450 had a little changed the cam and ported the heads and it go worse, fitted an emerald ecu got properly mapped and it like driving an normal car at low speed. Suggest you look at a mapping session or if buget allows ecu upgrade.
I have got to say TVR's should be smooth, end of story,when I sold my chim about 8 years ago it was smooth, I drove it everyday in traffic with no probs,I now have a 16year old precat griff and do the same. Now you know what it should be like the guys on here should be able to help you fix it.
Have you started with all the basics, throttle pot smooth, timing etc etc
