If your looking for traction control you might as well buy a new management system with it all built in.

Autronic and MBE have the facility for boost control, traction control, Anti Lag, launch control, (MBE has 8 different settings for launch) which I have on mine.

Launch control is well worth it but takes alot to setup properly.

You will also benefit from having a super controlable system for arround £1000 plus mapping of course.
