6k ECU and Collins Twin Piston Dump Valve

[WRXCLASSIC]

Hello,

I have a 6k 4 plug ECU for sale. It was used in the V3 WRX Classic which normally uses a Z4. The 6k produces more power. I also have an almost brand new Collins dump valve.

Please reply if you are interested, cheers.

What sort of sound do you get from the dump valve. The hiss or the 'squiggly' sound as i can best describe it :) also how much. Thanks
