this is what I have been looking for... I have an '03 and this is about where my boost gets too before it starts tapering down... I was starting to think I had a boost leak... I was getting frustrated thinking it was supposed to get to 1.5 but I could never get it there...

 

+whatevernumberwe'reupto

mine hits 1.6 bar but my gauge is off by .5psi

 

yea 05's are the same as MR's boost upped to 20.5. 10.5 hotside wastegate ports and turbine houseing are all diffrent from the 03's. that why all stock 05's should outperform any 03 stock evo's

 

I have the Defi BF gauge in my car and i hit 1.5 bars in second then drop down a bit

 

....05 WW GSR.....with Defi D Boost Gauge...


holds about 22 psi then drops to like 19......on WOT....

 

My stock 03 peak at 1.36bar with Blitz Dual TT, 05 should be higher which make sense

 

when i installed my boost gauge for the first time i was hitting 21 pounds and it was dropping to about 19, it was holding well.
