max but safe is gonna be about 15psi, yogs vr4( a well known member on this forum) runs 17psi, but i believe thats cause he made an adjustment, (can't remember what that adjustment is). i run 12 low 15 high.
be safe, don't exceed 15psi :nono:

I personally didnt run more than 14 when I was stock, 15 is getting a little high and 16 is a no no. I dont know yogs setup but I would assume if he is at 17 he has turbos, and fuel mods. The stock turbos are highly inefficent above 14.

Yeah - 14 to 15psi is going to be just fine on the stock tubos. The only reason I run a bit more on the Spyder is because I upgraded the fuel system. I haven't upgraded the turbos yet, but they are doing quite well up to 17psi. I'd like to get it on a dyno one of these days and find the optimal amount for its current setup though.
