Did you talk to the chip progammer or send a dyno plot in so the programmer could have a baseline reference? Seems to me a good thing you tossed it if you were running lean enough to get a knock. Proper programming will avoid these situations and net a good product. 
Must be that jumbly-wumbly thing happening again.
