flywheel

Morning So my car is going to have a gearbox rebuild and a lsd soon so i thinking is it worth have a lightweight flywheel put in at the same time is it really worth having one fitted is there a noticeable benefit ? any help will be appreciated Thanks

Well the problem is obvious but before you tell me to change my sensor it's a brand new one from renault sport is it possible the problem to be because I'm using lightweight flywheel and Helix 7.25 inch clutch kit ?
