All the info is in my journal thread "Adding Lightness" https://www.emiraforum.com/threads/adding-lightness.4796/page-5 but here's the dyno chart with the baseline run and Eventuri run:I'm encouraged by some of the reports, here. I just visited a local dyno shop today where I'll take both cars for a baseline once the heatwave breaks. It sounds like air flow may be a big bottleneck and the Eventuri sounds intriguing. I may start with that and then see whether cat delete and ECU changes are needed.
@Eagle7 - I'd be super interested to see your dyno results. Even if the conditions are somewhat incomparable it'd still be interesting. I'll plan to share my results for the two cars as well.
I'll add - the dyno shop asked me to look into whether the car has a "dyno mode". That's probably been answered elsewhere but figured since I'm posting...
The dyno operator for mine said he just had to sit in it on the dyno and "drive" it were his exact words, (just let it run I'm guessing) and after a bit the car recognized it was on the dyno, and it turned off the traction controls. He had it in track mode. The dyno was engaged and running, but the car was just idling basically. I think he sat there with it running like that for about a minute if I recall correctly. Might be different for a different type of dyno, but that worked for mine.
My results were with the 3rd cat still in place. No ECU changes were needed.
