Got a boost gauge? Post your peak boost numbers!
Quite a few people are now running with a P3 boost gauge or some other kind of boost gauge. I would be interested in seeing some peak boost numbers. It would be a good way to compare stock vs the various tunes (JB3, SSTT, Dinan, etc).
This weekend I hit 10.5PSI. I have the the BMW Performance Power Kit. Temp in the high-50s and I am at sea level. It can get pretty hot here in the summer. I will be watching the peak numbers to see how much the weather affects the boost. |

I know for sure I've hit the 14.1-14.3psi range on multiple occasions. Might have hit the 15's once when I was really going full out on a nice cool day.
10.5 is not too shabby though. |

On a cold day, I've hit about 9.6 psi of peak boost during a shift spike. I have a 6mt. During my stock dyno run in 4th gear, I saw 7.6 psi of sustained boost at peak. |

16.1 off of a quick WOT burst on map 7. I am sure I will press 18 on a sustained WOT run.

It's all in the mods. 2.0 with an 18ohm board intercooler meth straightpipes and intake I'm sure you can hit 20psi. Of course one of the biggest issues is getting those annoying little waste gates to hold the boost.
