Try the attached tune. I modified a lot that I don't like, pay attention to them on the difference report when you load it. Basic settings are all the same, just some tweaks that may or may not make any different.
Your spark advance is stuck at 29.1 degrees because thats what your 84kpa row is set to, although it's very slightly interpolating between 84 and 75. A quick google search tells me you must have dyno'd at 2000ft elevation. To put that in perspective, if you turbo charged your car, you'd need 3psi just to equal the horsepower of a naturally aspirated car at sea level, ignoring changes in torque curve.
I mainly updated more of the map because not only are you having power issues, but your idle sucks too. Hopefully my changes help. If you'd like, we can arrange a time for me to remote into your laptop to make sure the tune is actually working well.
The biggest change I'd recommend that I did NOT do, is changing to "include AFR". This makes your fueling calculation include your AFR target, so if you change it, your actual AFR should change with it. But that requires dividing (multiplying?) your entire VE table by your target before it's "right" again.
I will say, your drop in power does coincide with a dramatic change in VE, at 4000 you're at 64 with a decent AFR of 13:1. I would expect your VE to stay there or even drop of slightly with higher RPMs, as the BP runs out of breath. Instead, by redline, your VE is at 72, a 12.5% increase, with an AFR of 10.9. Smoothing that out may be all you need, but that's a long shot.
Alright Curly. Sorry for the delayed response, had to take care of our crotch goblin (our son). Did pulls this morning, the car felt a bit better and was more so angry in a good way. It wanted to go, it wanted to haul ***, I noticed the AFR stayed a bit more consistent, the idle is precise, and anything above 4600 felt, a tad different. I got the readings and will attach them.
Try this, richened up 3500-5000 and leaned out 6500 and up some more. May need more fuel removed still.
This time the vehicle felt more tame, more persistent throughout the range too. It could also be the fact that I was on a different ramp onto the toll way and it had a slight more of an incline. Here is my report Curly
Update: Took it to another tuner, they were confused about the whole tune alone, so they reworked everything and now I push out.... basically stock power as compared to my OEM ECU, this is mainly because they need to see how the engine holds up from a track day and want me to report back. They saw the old dyno and all the info and they were a bit shocked onto why the previous tuner claimed what they said before. Could I have pushed to 140 HP? It would've been nice, but there is a process I must follow to ensure the engine will make it through my torture test on the 20th.
