Personally, this is how I would wire everything up:
1) Boss SYB-05 Bass Synthesizer
2) Dunlop 105Q crybaby bass wah
3) Boss AW-3 Dynamic Wah
4) Boss LM-2B Bass limiter
5) Boss ODB-3 Bass Overdrive
6) Boss BF-3 Flanger
6) Boss CEB-3 Bass Chorus
8) Boss TU-2 tuner
Yes. I know there's two 6's. The flanger and chorus are interchangeable in that position. Putting the SYB-05 first gives it the best chance to track accurately, and gives the added bonus of the boss buffered bypass before the wah which isn't TBP and will load your signal. You could also move the AW-3 after the ODB-3 with the limiter following it if you like overdrive into filter sounds, or even move the ODB-3 to just after the SYB-05 and run it into the 105Q and AW-3. Personally I like my modulation at the end of the chain, with delay being the last thing in the signal path. The tuner can also double as a mute pedal with it at the end of the signal chain (I use a volume pedal for mute, as well as for tasty volume swells).
Tht's how I'd do it, but there's really no wrong way to hook up pedals unless you confuse the instrument and amp jacks at the beginning and end of your chain.
