considering the mhd flash on my 11' 335is

My car is bone stock with about 67k miles on it..Can it handle stage one with 91 octane?

what is the boost psi of this stage?

No your car will implode.

Seriously though, as long as your car has been well maintained and you data log to see how your car is running then it should be fine.

Once again you need to data log to tell if your car will handle.

You'll need new spark plugs unless you replaced them within the last 10k.

Expect to replace spark plugs if they have over 25K miles on them.

A few other weak links in your hardware may appear, like coil packs or even injectors.

You should also look into replacing your water pump around 75K miles too.

I think MHD Stage 1 91 octane run about 15-16 PSI tapering down to 11. (Not 100% sure but it would seem about right for that octane).
