Those who are reproting their boost, are you just eyeballing the boost gauge or are you logging the boost? Not to sound like a broken record, but eyeballing a boost gauge is not accurate and most gauges are usually off by about 1-2 psi.

 

I use an xede and the boost profile still fluctuates. Here is a table from multiple runs. The number in brackets is the average. The one above it is the maximum boost.

 

NJ -- I had my boost logged with an Innovative boost setup while my car was on the dyno....Interestingly, my autometer gauge was almost perfect compared to the Innovative readings. I will be installing the Zeitronix WB and Boost sensor this weekend for further refinement.
