Block 032 - "duty cycle" -- Is this talking about injector duty cycle?
The "duty cycle" reading only goes to 37%.. even at WOT @ 6800 rpm in 3rd! The car is running 895-900 * EGT's so i'm trying to figure out why.
K04's on stock chip + 5 bar fpr + dp's + VM3 + stock filter/piggie air box.

block 32 is more MAF/fuel related...
... some people call them fuel trim numbers. The numbers you see in there should be between -5% and +5%. outside of those limits and I'd say you have a leak.
The first number is fuel trim at idle and the second number is the fuel trim at partial load. In the S4 this is repeated for the second bank i think.
If your idle numbers are out of spec, I'd say you have a vacuum leak. if the partial load numbers are out of spec you have an intake leak on the high pressure side of the turbo. If both are out of spec, maybe your maf.
Reset the ecu clears the learned values and you can see if your car relearns some bad numbers. If so, check your maf and/or clean it.

Well, i am running a 5 bar FPR that the computer doesnt know about.
How will i know where i have a vacume leak? I already suspect i have a boost leak on the pressure side of the intake.
