Where do you guys drive 140 mph multiple times to tune? I think I'd kill myself or someone else.
I don't use backroads, 'cause ya never know...deer, kids, beavers, whatever. Plus tiny 45 MPH transitional bumps turn into, "jack the ass end up in the air, hella scared, ski slopes" at speeds approaching 100. I usually use a lightly traveled section of highway that is not really monitored @ 1am. No on-ramps, straight as an arrow with no place for cops to hide. That and my Valentine One hasn't failed me yet. I usually pull from 3K in 4th gear until 7K~7500 and do a lazy shift to 5th to come out of warp. Doesn't take a lot of room, minimal tirespin, and I can get some good datalogs.
For the topic starter, stroker6 has some good gouge. The only thing that I personally do different is lean it out a tad from 5500 on up (12:1). It also matters what your running for a turbo setup (as the wrong A/F can kill spoolup). Guessing by your nick, I would say twins
. Whenever I tune, I shoot for 14.7 on cruise until 150kpa, dropping to 13:1 until 170 kpa, 12.2:1 until 200 kpa and 11.5~11.8:1 from there on up, leaning out a little up top as previously noted. If you're an Imperial kind of guy, just divided KPA/6.894 to give you the pressure in PSI (and subract an atmosphere, -14.7).
