3 bar installed. Feels to me like the throttle response is much better with the baro breakout.
Also... the 3-bar is measuring 154 kpa peak, which means my boost gauge is probably not very accurate. :( AEM boost gauge only shows 6.6 psi max, but 154 kpa minus baro is about 7.6 psi.
I think there is still some gains to be had in terms of tweaking the timing.
There's still some odd (to me) KR at the top end of the rpm range, and some light KR in the middle rpms too at times. I'm not confident it's for real... a couple of the runs it seemed to go away, but other runs with same settings it was there. Some experimentation with timing again should help. I'll try ramping up and down from my current and see where it takes me. Maybe I can run a bit more timing after all.
I'll play with the PE again too. Was taking some baby steps in increasing the PE and watching low side fuel.
So, up to this point, I feel very good about the tuning changes. Learned a lot. Not quite 100% sure where I want to go next. Prob try to get back to the track for another pass or three before I make any major changes, meaning new hardware.
Hope someone else finds this useful. I'll continue to post anything I find significant. I feel like there's a lot of other folks out there that could save hundreds of dollars on custom tuning, or are interested in at least making their canned tune safer. Is my tune as good as on a dyno? Almost certainly not, but it was a lot of fun, and feel I have a much better understanding if I ever do get access to one. Or at the very least I can understand and validate changes someone else might want to make to the tune if I take it somewhere.
Some eye candy from the very last run I did this AM:
