102mm BBK throttle body

[tmizer]

Just an fyi for anyone employing "search" to good use, thought I'd post what is working (so far as I can tell) for my particular setup:

After numerous evenings after work, I finally got one of the new 102mm BBK throttle bodies (p/n 1790) to respond. While the tune is still a work in progress, and I'm sure the pro's would probably rip it apart, the long and short of it was:

ETC Area Scalar = 6750
Effective Area:
Max = 6750
Min = 150
Max Fail = 525
Min Fail = 330

Motor is a 415 stroker,
10.1:1 compression, .028/.030 gap rings (nitrous)
LSA ported heads (~350 cfm intake ports)
Port matched Holley Hi-ram intake manifold
95 lb FIC injectors
Twin Walbro 267 pumps
Manifold referenced return system
238/255 116+5 LSA .615 .632 cam
Vacuum pump (so no pcv line routings to mess up air metering)
102mm Nitrous Outlet plate
102mm BBK throttle body (that uses the OEM stepper motor)
