I searched around a bit but didn't see anything...hoping someone can just tell me off-hand.

At what boost level do I need to start worrying about leaning out too much with stock injectors/pump? I'm seeing boost creep spikes into the 13-14psi range on these cold mornings and don't want to damage anything. I have an old XS engineering FC that should be enrichening everything, but I have no idea what duty cycle my injectors are seeing.

Thanks in advance.

 

the stock ecu stops feeding the rear rotor after 14.7 psi I believe so anthing above this is when you would lean out and pop your motor...better lay off it a little bit.
