S1 Agg. is ~15, I have got into the ~16 psi range on some logs.

S1+ Agg. ~17, with some peaks at 18.5

well it wont hurt. I do know the v401 MAPs are more aggressive than the v300 MAPs. You may also be getting throttle closures due to "over boost" which I can't tell until we get some better logs. If so its an easy fix with ATR, as reported with other users...

FYI, I hit ~19 psi mid range with my stock turbo's. PTF Pro Tune FTW!

overall not too bad. It appears some throttle closures when you hit ~16 psi. (log 17) Try to get better, clean logs so we can look again. Timing corrections are not bad as well.

Try that pedal spacer, it will make logging a much more, exciting experience.

How do you guys deal with the O2 cel light as I am about to install Cobb today.
Does it matter if I drive around with the cel for a while also ?

You're fine to drive around with cat ineffeciency codes until you can get the AP installed. Once the AP is installed any of the OTS stage 2 or stage 2+ maps will get rid of the CEL. Using ATR you can also disable the OBD2 readyness checks for any of the maps if you want.

Sounds good but I have some work on Tuesday but maybe late afternoon or any other day in the afternoon. I'll still buy the beer.

I'm gonna be getting dyno'd in afternoon @ Undercover Performance (~1/2 hr from Philly) & will be in South Jersey for a good portion of the day. If you're interested send me a PM and maybe we can figure something out

That is a VERY good looking log
You should add STFTs and LTFTs to be sure your trims are in good shape. However, your AFRs are good so your trims aren't maxxed.

The only thing i see that isn't perfect is that you are having a slight overboost condition between 3600rpms and 4100rpms, however it wasn't enough to cause a dip in TPS so i wouldn't worry about but I would keep an eye on that in future logs just to be sure.

Thanks! What should I remove from the log to make room for LTFT and STFT?

I may switch back to the e30 map and get a few logs in a few days, now that the v4.03 map is available.

OH! and I forgot to say I'm in Denver so I'm at about 5400 elevation?
