2500 to 3400 ish... at WOT/ some partial throttle it dips into the 15's then finally kicks in and begins to slim down to low 13's where ive set it at...

... my solutions are minor in terms of what i need to go back and adjust even though ive tried a few things and no luck yet. Im gona play with the numbers tonight to see if i can fix everything and have it be linear like the rest of the graph. im probably going to adjust the timing/a-f in that low range and recheck voltage readings.

I think what you are seeing has more to do with the rate of opening of the throttle body. You command one thing, load wants another you get something in the middle.
DBW is ___.
You see this a lot on tip in with the tC when you are tuning with standalone.
At that RPM it's probably not that big of a deal. Can you change your tip in rate? What are you tuning on?
By the way, good power, I'd love to see what NA would do if you carried out the red-line, although it looks like power flattens out near red-line.....

yea DBW is fkn garbage i hate it...
im debating on picking up one of those TWP throttle controllers to help rectify the lag and also NOT have the butterfly stuck at 80%... if i can squeeze the buttery fly fully open like any other dam normal car i can make some more power probably... the curve is flat at the end because of me not wanting to push it hard close to redline... i havent taken the car far enough yet and havent wanted to push it to much right now since its still freshly put back together... i posted specs on my 200 whp thread.
Im gona bump it up to 7k soon and keep it there... and also fix a few things... the stock midpipe is whats killing me making power right now at higher level.. theres only so much air that dam straw pipe can push out at certain speeds lol

Keep saving Crush, you know you NEED one.
That's the beauty of this unit, I can easily tune it myself. Dezod supplies the base calibration for the 2AZ-FE, my injector flow rate, battery offset, etc. and all I have to do is set my desired AFRs and timing. While a pro tuner could certainly get more power than I will by fine tuning the AFRs, EGT and timing on a dyno, I can set safe AFRs and simply pull some timing where I see the ECU already doing it based on knock. It's not like the FIC where you have to fine tune every cell value in the fuel map to acheive your desired AFR. The X1 does that based on AFR sensor feedback the same as the oem ECU does in closed loop.
FWIW, one of the many factors that sold me on this unit was a FIC cost breakdown I did. I live in MD so P-Tuning would be a logical choice for tuning so I used their pricing.
FIC - $300
Boomslang PnP harness - $500 (XB2)
First tune at P-Tuning - $550
Subsequent re-tunes if I change anything - $400
Total FIC cost after initial tune and one re-tune for changing injectors, exhaust, turbo, boost level, etc. - $1750
Another contributing factor was a conversation I had with Gadget from URD about this unit. Gadget knows this unit very well and uses it with URD's custom supercharger kits. What he told me about it is too much to go into right now but suffice to say that he confirmed everything Paul and Don have said about it and recommended it without any reservation. This despite the fact that URD sells their own piggybacks and the excellent Map-ECU2 unit as well. We also discussed where AEM went wrong with the FIC but that is another topic.
