Got my car tuned last weekend, basically running a Mazdaspeed miata turbo system with FM little enchilada and stand-alone. 14psi, 225 horsepower and 216 lbs-feet of torque. It’s a fun little car!

Hmmm. I am running a pierburg electronic boost controller. I still want to play with the open loop settings on the MBC more. I was trying to get it so that the wastegate could remain closed as long as possible in the lower rev range so to spook up quicker, then start opening at 14 psi, then at 6,000 rpm, close again.

From my experience, these little turbos really nose dive on boost when they are spun over 6,500 rpms, on a manual boost controller i would lose 2-2.5 lbs of boost from 6.5k to redline. Not anymore.

my tuner wanted to dial in a bit more timing, 230 rear wheel horsepower was definitely achievable he believed, but I wanted to be conservative on it. The 99-00 intake manifold on my 1999 10th Anniversary definitely is the way to go.

Another problem I have had is spark blow out, I am going try replacing the bkr7e11’s with some extended plugs like FM sells. My IAT’s were fine, but I sorta wonder if it would have been better to just dial down the boost to 12 psi and run more timing...

Yeah, 14psi is kinda pointless to make past 6k, that turbo just isn’t going to flow. I would have like to seen what numbers could be made just running 12 lbs of boost.
