Thats no good! I thought the 08.5 pumps were supposed to hold up decently compared to earlier models? How many miles do you have on the car?
 
i have about 18.5k

Yeah you look to be needing a FP. Of more concern is your High AFR's under WOT. When you are getting the fuel, you're doing almost 13AFR. To me that is more of an issue and just begging to pop your motor. I would not go WOT anymore on that MAP friend.
 
The log is almost useless. Too many items...

If you want to check FP, log only RPM, boost, AFR and FP.

useless cause theres too many items? thats ridiculous. if anything id say its more useful since there is more information.
but thanks for the input(piss)

+1 all u rlly need to look at is airfuel, u could look at it while ur runnin the car. at wot the afr should be at 11 all the way throuh the gear while urs looks like its almost at 13... u should def get a pump .. but did u know that if u run the car a little leaner and throw more boost at it the car will actually be faster cause with that the car pulls timing.. my car was pulling like 8degrees of timing at one point.

Do you realize that it takes a certain amount of time to get each individual data reading?

The logging device sends a request to the ECU for RPM (for example). It then must wait for the ECU to respond with the requested data.

If there are too many items being logged, there is poor time correlation between the data items on each line. In that case, the data obviously becomes meaningless.
