hi whats the setting for the splitter valve for a remapped octavia vrs mk1 the managment light keeps coming on set for a standard car. im just thinking mabye it could have been mapped before i got it ??

You need to get the correct DV fitted!

Adjusting it won't make much difference even on a remapped car (normally 2 clicks clockwise for every p.s.i it boosts at, remapped cars are approx 18p.s.i -36 clicks).

In addition any amount of adjustment won't stop the engine light coming on!!
