http://www.evans-tuning.com/ecommerce/b ... enoid.html I think it will run with ectune but anyone use it yet? Is this mac solenoid allso and can it found somewhere else cheaper? I paid like $30 my 3 port mac solenoid, and its maxing out 27psi with 12psi spring.

i personally dont see too much of a benefit other than letting more air density into the top port of the wastegate to allow the wastegate to keep up with the rapid change in boost/air volume pressures.

you can buy MAC products from your local automation and supply company. The difficult thing is going to be working with them to track down a suitable valve as they have plenty of options. If it's not a commonly used valve that they have on their shelf, be prepaired to wait for 4+weeks to get it from the factory. Edit: Didn't realize you were in Finland, but MAC still lists a vendor Lektar Oy P.O. Box 92, FI-00710 Helsinki Hiekkakiventie 7 FI-00710 Helsinki 358 09 413 55 100 fax 358 09 413 55 120 lektar

I think its this http://macvalves.com/valves/4-way-valves/46-series/ I found at HT this:

try lower frequencies to get more boost out of it

Im running 31hz now so i have room to lower it. I might test it first because i dont need much more than now.
