I've seen mixed reviews as well, but it's my understanding that the 3-stage uses the knock sensor to creep up on the detonation threshhold instead of using the wideband o2 sensor. The guy who bought my business, 360 performance, had a 3-stage but sold it about 2 weeks ago. The CRX is a better shape and the VX engine or 3-stage would perform better in that. You're probably out of school now, but keep in touch and I'll see what happens. Word is they have a small wind tunnel there for models, which would be awesome...if true?
