Heh, those are burried down there.
Not sure about the tach, but mine have bounced on some coils and not on others. It seems one of the leading coils in the red REPU and the trailing coil in the GLC would cause the tach to read funny. As long as they don't misfire, I'm ok with them. I moved the tach wire to one of the leading coils in the GLC and it read fine. I think it was too close to the alt because the trailing coil was mounted to the top of the rotor housing to one of the rats nest threaded holes.
I test fired the freshly rebuilt R5 13B in my red REPU yesterday with a carb I just swapped onto it. The carb still had fresh gas in it so I pulled the choke and cranked it. Vroom! Heh, there is no fuel system, exhaust system, or cooling system. Needless to say, I didn't let run very long, even if it wanted to (there is about a minute worth of gas in the float bowls, but all I was checking for is oil pressure, so when it got up to about 80 or so, I was satisfied and shut off the engine).
Yes, the dual leading sparks may somehow cause the engine's exhaust pulses to quiet each other down better than single leading sparks. Others have said their cars got quieter with direct fire systems as well. Yes, the exhuast always smells less fragrant with direct fire.
Gas mileage should be better since more gas is getting burned.
Why would you want higher octane? It burns slower. There is no need as far as I know, plus lower is cheaper. As far as I know, nothing is gained, and something (power, gas mileage) may be lost. I'm sure others will add their opinions.

do I need to hook that little...thing with the bullet connector...into the 12V on all 3 coils??
I just left it hooked into the factory spot...figured it would be fine...and would still stop interference...since i'm using the factory 12V lines to run the coils
hmm...crap...I dunno...it doesn't do it after i rev it a bit...so...I guess if thats the worst problem I have...i'm just not going to worry about it
The engine isn't revving around...its just the tach bouncing around a bit
