Installed the Walbro 190lph-hp pump tonight and took it out for a spin. I didn't replace the carpet/insulation over the rear deck so the pump's really loud but I didn't notice any detonation. Hopefully get things all sorted out during the Houston dyno meet tomorrow.

Damn, I shoulda chimed in sooner. Yeah, stock 99' fuel systems are a JOKE. I'd plan on upgrading it to a return system in the future. POPSTOY on miata.net had to put a 255HP in his 99' to hold fuel pressure to redline at 170whp. 190HP wouldn't do it. Pretty shitty fuel system. I changed my pump twice trying to "fix" my loosing fuel pressure. Still looses pressure at high load and the amount of fluxuation varies, which makes tuning the top end of my fuel maps impossible. Got a Mallory 30-100PSI 1:1 fuel pressure regulator I'm going to use to convert to a return style setup this summer. For now, I tune uber rich so when the system sucks I don't go too lean. And I'm still N/A...

Aside from my feaux personality on the internet, I don't exist. No social security #, a funeral a few years ago, and more government issued feaux ID's than you've seen in your life.
That was worth reading 3 times...at least!
