Gents, the lower dyno is for comparison purposes only, nothing quantitative. This dyno reads LOW compared to the others I've used in the area. MX5 we did an hour before this was 135 pre tune, 149 after tune. This is with headers, exhaust, intake...they normally do 165+ with that combo. The lower number shows a high reading for two reasons:
1: The baseline is the BEST stock run of a strong car. I made sure to break it in with launch control and smooth rev limits at the time of delivery
But we have many runs with it that are worse. I just put up the best one so nobody is disappointed when they do their own dyno with my tune.
2: It was colder that day. Forget the dyno corrections; if it is colder, a higher compression car will do better even when you consider the STD/SAE stuff. Dyno can compensate for baro, humidity, and temp. Not how much advance the car can run.
I'm glad others have put up the dynos because we spent about 4 hours on the dyno that day, and only one of many tunes allowed us to get that peak, which should be the norm IMO. I'm a 100% confident we will get it smoothed but not 100% it could be done with the stock port injectors.
PSI as adeets said I'm not 100% on, I was busy watching AFRs and have no control over that. Please keep it civil this is not a measuring contest just sharing what we can do with the platform. Having had all kinds of cars over the years I've not been excited by anything since first getting the miata. To see us being able to get 250+ whp on the stock motor in just a few hours of tuning blows me away. It took much more than that with the MX-5 but at least this time we have EcuTek to work with so that frees me up greatly to tune vs disassembly.
Hopefully we'll keep seeing more FI/NA setups to work with because with each we learn more and more. If not for the turbo BRZ I must have 40+ hours into between emails/tunes/travel/dyno, this would have taken much longer. I'd really like to see what the limit is of the stock motor on this with a proper tune.
