As title says whats the best coloured spring to get for my car i have a compbrake DV? It has a shark stage 1 remap but i have been suffering flat spots recently so iam replacing the cheaper parts first to see of they solve my problem.

Hi there, generally when a remap is done, the Green spring is replaced by a yellow one. Some folks still get away with green. I did'nt and when swapped with yellow cured a similar issue to yours.

Valve Spring color coding

Green - 6-8 PSI

Yellow - 10-12 PSI

Blue - 14-16 PSI

Red - 18-20 PSI

Quote from there site and link

Please Note:

The quoted spring pressure (Psi) relates to the un-assisted clamping force of the spring and should NOT be taken as an equivalent to boost pressure when determining suitability. Once a valve is fitted to a car it is subjected to various pressures that act upon the diaphragm or piston to aid its respective ability to seal or hold boost. An example of this, would be when using a FMCL007P valve on a 1.8T engine as found in the TT 225hp. The boost pressure on a "chipped" car can peak at 26psi. The recommended spring would be the Green or Yellow

Perhaps this could be a sticky thread as is asked quite a few times.

Thanks bowders ill go ahead and order a yellow spring.

My mate had to use a yellow spring from the off

I have the compbrake dv and i think i chucked the stiffer spring away. I had a check this morning the spring is quite soft thats in my dv so iam hoping the yellow one will cure my problem :-)
