Problem with that is running lean can show HP. With nitrous running lean is dangerous. You can be pig rich on the low end and completely lean out on the big end. Or have a lean stumble and then go pig rich,.. thats how carbs are.

I'm no expert but I know my way around a carb. I tune my carb by reading the plugs. If you know and understand how to read them,.. they can show you if your advance comes on too soon, lean on the low end,.. lean on the big end or too rich vice versa. I've never done it with a wide band,.. that would be a new experience for me. But I imagine a simple wide band and reading the plugs will get you 99% of where you would be with a dyno for a bit less money. If thats not a problem for you or you really just want to hit the dyno to have some numbers I can understand that. They will (Or should) have a tail pipe sniffer at the dyno to show if you are lean or not for cars with out a wide band bung.

My method would involve me hitting a 4 lane road not far from my house. Depending on my rear gear I would do either a 2nd or 3rd gear pull to what ever my max RPM would be. Come back to the house and pull the plugs to read them. Make adjustments,.. clean the plugs and reinstall them. Rinse and repeat. Once I got it to where the plugs were reading good then I hit the track for a TnT night and complete final tweaks at the track based on MPH,.. not ET. MPH shows HP,.. I drive a stick and my ET's can be inconsistent to say the least. But I know if my MPH climbs,.. I'm making more HP. The ET's will depend on my launch and shifting skills. Thats the old school way that I was taught. If someone does it differently or if there is a better way I'm all ears.
