Speed Flatlining? Feels like I hit a wall

[Colorado_Stinger]

Hey @Terry@BMS i am coming across this weird problem with my car now that I have gone to e30. Whenever I launch the car it feels amazing but i flatline, it feels as if I have hit a wall towards the top end of the lower geas. I can also hear my car let off boost into atmo as if I overboosted or something. Was wondering if maybe you could take a look at this log. This log was a launch and I was letting the car shift by itself.

Please post the csv file, not a picture. There are several other things we need to look at that you didn't include.

Is this what you are looking for?

Yes, thank you. OK....
Your issue right now is you're running lean, dangerous lean. Once you went to E30, it requires much more fuel to satisfy the AFR. There are two tell tail signs that the engine is struggling.
1. Trims are maxed out and Fuel enrichment can't keep up
2. Your actual AFR is in the 15's until 3rd gear!
Please tone down that boost. You're running over 23 psi with no additional fuel source like WMI or CPI. I would also take DWP back to 0 until you can get a clean log without hurting the engine.
Last, your timing corrections are a bit high which is also an indication that there's not enough octane to satisfy the boost you're requesting. I would keep boost at or below 21 for now and consider CPI as an upgrade. That will allow up to E40 or more without running lean or hurting your engine.

Okay thank you so much. CPI was the next thing I was gonna buy as someone down in texas recommended it as well. Thank you again for your time and I will be going back to map 2 when I run out of e30. Thank you again!
