This is the setup this far. I have a hood installed now with a proper pre heat. I’ll add them pictures also

From your photo, it looks like your pan is made of fairly thick stainless. If so, that can reduce evaporation efficiency quite a bit.
And don't forget to put a drip tray to catch all the condensate on the preheater tubes. If they drip back in to your pan, you have lost all the gains of having a pre heater.

Going out the sidewall with 2 elbows also reduces your draft a good bit. Can you go straight up through the roof and above the peak of the building?

I’ve install a Chanel all along the bottom of the hood. Is that what u guys are talking about or do I need something else added to the hood
And another thing is if I installed Chanel say a 4 inch angle in the arch would that make the smoke and heat to roll and create more boiling rate. Instead of just straight out the arch

When the hot steam hits your cold copper pipes filled with sap it will create a lot of condensation in the process. If you don't catch this condensation coming off the copper pipes it will drip back into your evap pan and adding water to your pan. Most hoods have a catch under the pre-heater that is pitched toward one of the hood gutters to catch the condensate so it doesn't go back into your pan.

I am achieving 14gph with a 2x4 WF Mason divided pan. This is on a 275 gal oil tank evaporator with AUF. Using an old squirrel cage blower from a Beckett Furnace. Ripped the guts out and wired it in with a switch. World of difference. But as others have mentioned, wood goes faster but so does the water.
