Cold but dry. I'll try to get some footage going :)

Who did your cat? If it was a weld in cat and a shop welded it you might want to check your flanges. The shop i used simply cut off the old exhaust and welded in the new cat reusing the old flange with the tiny 2.25" hole in the process. When it warms up i gotta open er up and drill out the hole on the flange.

Being that I have 225-50-15 RS2s and spin the wheels at 18ish psi, I think that your boost gauge is at least 10psi off.

Either that or your miata is some derivative of jtothawhat's. Preternaturally amazing.

Hi everyone again im a noob on turbo miata. I did some research I got a FM2 kit with link for managment. I'm currently running around 180whp at 10psi. My goal is pretty simple, I want 250whp in quick spool and low psi, i wanna keep it all 10-14psi range. Now my question is, what should i upgrade? Or should i not use FM kit and go for something else.

I think it would be best if you kill yourself, and then buy your car a megasquirt.

Both, mechanical dash gauge and the 3bar map gauge in adaptronic both show the same thing. :squint:

How are you guys mounting cams? I tried to take a video today but holding the cam with 1 hand while trying to shift etc results in bad video.

I'd do a few easy things like clean the filter and check/replace plugs with NGK 3033 with a .030" gap. That should set you up for tuning. When you did your dyno run, did they take AFRs? What were they?

A 94 1.8 @ 10psi should net you ~200-210rwhp. What kind of dyno was it? If you were on a Mustang dyno, then the 180rwhp sound right and would be 220-230rwhp on a Dynojet. If you're running the tune that FM put on it, it will be for 91oct gas at a higher altitude and will be very conservative. I went from 225rwhp to 250rwhp going from FM's tune from having a local tuner in Atlanta tinker with mine (93oct and 900ft altitude).
