| The Z hasn't been my daily driver for a few years now so the time I get to work on it and just plain drive it is limited. About 3 1/2 years ago I discovered I had A/F issues and ended up doing a bunch of work including installing a wideband. Things seemed fixed/generally fine but the two times I went to try to confirm on the dyno, weirdness prevailed and the runs were never clean, with no real indication of what was wrong, though I have my suspicions (operator error). Today I got an ECU tune by Seb and Greg from SpecialtyZ at a tune/dyno day in Denver. Finally, clean runs, and I'm super happy with the results. https://www.flickr.com/photos/andrewdavidoff/22261882211 FTR I plan to run max 15psi, not the 17psi in the biggest run. Just wanted to share. It feels good to finally know "for sure". While I'm at it, my continued thanks for this site and everyone who supports it. And on the off chance that any of the admins are viewing this, I'd love to fix the busted link to my ride photo in my profile (404 [ http://www.twinturbo.net/ttnetrides/655/655header.jpg ]). Andy
