oh don't listen to other smart guys....we have one of the biggest stock turbos on a car so 26 psi is not that high at all...people have pushed the stock turbo to 30+..its not very efficient at that much boost but it still makes her scoot!! idiots tell me all the time that 26psi is gonna blow my motor....usually driving a HEMI or some BS lmao....I was having boost control issues on stage 2 cobb last year and was overboosting to about 32 psi...made all 4 wheels spin rolling in 2nd on dry pavement...stuff like that is what should give concern...

The files are excel and says "invalid file" when trying to do an attachment? hmm
Can you post a line or two of your 3rd gear log around the peak boost area?

Also I feel like I'm getting less miles per gallon. But it could be me trying to make all these logs..... I'm going to wait until I get bored to put on the intake again or wait until I put on a TBE.

Your peak boost is only 23psi. All looks good to me based only on that screen shot. What are your LTFT during cruise and idle?

This is a 3rd gear pull from 3500 rpm to red line. I was worried about my 1st and 2nd gear boost levels reaching a high of 28psi. That is what worried me a bit. I can post some of those. Give me a day.

You didn't tamper with boost pills did you?
Check all vacuum lines?
