Hi all, I've linked (hopefully) a datalog from driving in traffic. I'm new to this so it's probably useless. Maybe you guys could give me some pointers on what to log.

 

Details-

2005 LGT MT5 128,000 miles

Cobb AP Stage 2 93 octane map

AVO catted DP

AVO Up

Bulletproof TMIC

 

 

 

About 8 months ago I noticed a slight stumble at part throttle between 2-3k RPM. (I have been through the stumble thread). Very intermittent. I've never logged it.

 

About 6 months ago I started getting some stumbling at idle, usually when the fans/AC compressor kicks on. I have had a few stalls but not since I replaced the neutral switch (more on that later).

 

I have also noticed that fuel mileage has dropped about 1 mpg during this time. Power seems the same, though it's hard to know.

 

Cruise control has never worked. It surges and then the cruise light flashes. No CEL.

 

Things I've done in the last year-

-Gates tbelt kit with water pump.

-Replaced blue T with metal one

-Replaced all accessible vacuum lines and zip-tied

-Replaced turbo inlet (oem)

-Replaced MAF sensor

-Replaced AF sensor

-Replaced plugs

-Replaced neutral safety switch (this was definitely bad, unlike the MAF and AF

-Made a boost leak tester and found no leaks

-Sprayed about 2 cans of starting fluid around engine bay while watching AF correction and have found no leaks

-Cleaned MAF several times (paper filter)

-Inspected OCVs

 

I have not done a leakdown test. This is my next step but I just don't have time right now.

 

Any help or guidance would be greatly appreciated.
