Default 91 Miata Turbo

Well, I have been slowly getting my Miata to the power level I want. Finally got the AEM EMS installed, and did a few street tunes to make it driveable. We put it on the dyno this evening to see if there was any fine tuning we needed to do...it was almost perfect, running 11-10.8 A/F, with a rich area between 3-4k. It is tuned to be safe right now, we'll work on it making more power when we turn up the boost. It's currently only running off the 5.5psi wastegate.

The red line was running 7psi with some basic bandaids (fuel/timing piggybacks).

Big difference with 1.5psi less.

Later this week we'll be installing the EBC and running 12-15psi (or more).

Nice numbers ray! One question though; why are you seeing boost so late on the rpm band? What turbo are you using?

Stock Greddy turbo. Not sure what you mean by making boost late, it makes boost really early.

I'm seeing 10psi by 4,500 rpms in mine and I have a T3/T4 installed. That's why I asked about boost.
