As soon as the temp is above 60 C, you’ll get full boost. But like I said before; > [@Onyx Z32](#): > > I wouldn’t boost the car at all. He still has an NA fuel pump… [HERE](http://www.nyspeed.com/forums/showpost.php?p=38077&postcount=8) > [@90NA300ZX](#): > > …and the reason for low/safety boost is the computer realizing it’s not getting enough fuel for that kinda boost… No… [Click HERE for a list of what causes safety boost.](http://www.twinturbo.net/ttnetfaq/FAQpages/safetyboost.html) Run ECU Diagnosis [(Click HERE)](http://www.ttzd.com/tech/diagnostictech.html) before you go insane speculating about what it could be. > [@nitroinsane](#): > > … my question is to onyx or any other 300z guy. would limp mode only be 5 psi. usually in limp mode it wouldnt allow it to boost right? which this thing strikes me odd… Safety Boost = 5-6PSI. Safety Boost doesn’t stop the car from building boost completely. But that small drop makes for a large power decrease, relative to the stock output of the car (around 50whp, so around 20% whp drop.) Safety Boost changes the fuel maps as well. > [@boardjnky4](#): > > ummm…im in the process of doing my head gasket right now, and you do not have to pull the motor to do it… :word: Pulling the motor would be harder than just doing the gaskets in-car. --- _[View the full topic](https://forums.speedlife.net/t/its-dead/2317)._
