Hello Everyone,

VTX1800c 2002 18.000 miles
Vance Hines straight
Hyper-charger with K&N
Power commander III
EFI 2000

My autonomy is terrible, 80 miles with a full gas tank light for gas starts at 70 , spark plugs look good...
I just lower the commander settings on low and mid.. and here you can see the EFI setting any suggestion
Hood Motor vehicle Automotive lighting Automotive design Automotive tire
Rectangle Font Circle Technology Electric blue

before i change it also attached is the manual suggestion

Mine is set to 2 - 0.5 - 0

My desire for this was to simply reduce decel popping.
They aren’t much good at all for trying to add power, you just end up wasting fuel.

Why do you need a PC-III AND a 2000? Either, or , should be sufficient. Explain please.

I got the bike with very low miles, the previous owner just did a bunch of upgrades without thinking… one of them PC-III and the 2000 efi
Bikes is mint… but is fuel consumption is terrible mileage at best 80 miles on tank.
Spark plugs look perfect
Review and upload the correct map for the settings but still bad mileage
So my only take is removed this EFI2000 as it makes no sense having both and looks like the cause for terrible mileage
