How do i log these values? MAF values, O2 voltages, throttle angle, requested boost, actual boost.
#2
Select -> 01-Engine -> Measuring Blocks
Group 003 should have RPM, MAF, Throttle Angle, and Ignition Timing.
Group 115 should have RPM, Load, specified MAP, and actual MAP. "Boost" is MAP minus ambient pressure.

Any help diagnosing this would be great. I am assuming it's my primary 02's that are fried...? And if so why would the y die so quickly? 3500 miles with piggies with no cats would that do the trick? All i know is that my car was fast and now its a dog. ANy help would be great! TIA -Rob

that looks like ideling capture. Have someone ride with you, do a 2nd gear pull from 1000 to redline
have them start the log just before you take off, and after you let off or shift to 3rd.
You need a good hard pull to see actual/requested boost, and how much air is moving past the MAF sensor during the motor's loading.

#7
if you didn't "clear the error codes" take a look at "readiness"
see if all the windows show "PASSED"
Sometimes those can point to a problem.
If you clear the codes option though, it will reset those and you'll either need to drive around or run the diagnostics procedures on the components to get them from Not Ready to Passed.
