Default Is 9psi pushing it on a stock LS?

I plan on running my car at 6psi, but would turning it up to around 9 every now and then be putting too much stress on it?

My fuel setup is the MF2 and I have a BTM for timing.

Also, this would only be a track/race thing, not for every day.

Don't quote me on this, but every thing I have ever heard about the b18b is that its safe to run 10 psi stock, 12 psi with good fuel tuning.

I plan to run 10 psi daily when I get my turbo, but I will start out with a standalone, 550s, and a walbro fuel pump, so I think it will be just fine and dandy.

SDS EIC
10psi daily! for the last 6months
Yes, I love the SDS EIC. The MF2 should hold up fine for 9 psi though.. just make sure you get both boost levels run through a dyno and tune carefully before doing it daily.
