I'd really like to know if this is possible, as it is what I want to do with mine. but from the searching I've done it seems the stock solenoid has a max boost of 8psi, so putting anything more than that into it will become pointless as it would reduce it anyway....(i think! i hope I'm wrong!)
Installed my turbotech controller today, very easy to do thanks to the great threads here!!!
The only problem is that when i put my foot down, boost comes up to about 10 psi then drops to about 9 and settles in the middle. it is solid after this without change...Is this a sign of a leak somewhere or what??
Aside from that, boost comes on noticably quicker but I don't know if it feels like more boost or not, though I haven't been too hard on it yet..
Here's a pic to show it is installed correctly.
