So are you liking the LM-2? Are you using the rpm module also? I am messing with the six bbl on a 512 wedge and have realized I need a wide band gauge. I have posted questions about wide bands on 2 different websites. The guys on here like the LM-2 but on the other forum nothing but bad reviews and they recommend the Daytona WEGO. How has your experience been?

You still haven't answered the question unless I missed it,did you do anything with the jetting in the end carbs ? I would "assume" that if you have anything more than a cam with specs close to a sixpack cam,you would be lean as soon as you got into the throttle especially with a 540 cu in motor,you will have to change the end carb jetting.

There is still a bog, not nearly as bad, but does need to be addressed. But when they kick in, it's a beast!

I'm going to work with more springs tomorrow, and see if that solves it. hopefully it's as easy as that.

It's interesting, I expected it to be lean as well.

I have 66 jets in the center carb, have not touched a thing on the outboard carbs.

Reading about 12.6:1 at WOT. If thats the case, I actually need to lean it out a bit.

I have an AEM wide band gauge in the car. I don't remember which model it is, would have to look it up. I do believe it has a USB port on it, so I may look into playing with that.

I agree. If you have a stumble/bog/hesitation and you change the vacum pod springs and it gets better then I agree slowing them up will not let them slam open to fast before the circuits in the end carbs start to work and deliver fuel. If you made no fuel changes but stop a lean bog you are just slowing up the end carbs. Course it sounds like the end carbs may be to lean for your combo and need more jet and so on. Good luck with it as adding the 02 is a good help and you are learning more about the setup as you go along. When you get into 540 Hemi's and add a six pack normal 440 six pack jetting wont work.
