Bob at BPC says they is no fuel trim with the tune.
I'm struggling to understand why my gas mileage got so bad since I plugged in the DISAs.
Gas mileage was fine when the tune was installed but the DISAs weren't plugged in.
Doesn't smell like gas, just seems like a guzzler.

That does seem low. But remember the extra torque developed with the Disa valves does not come free. If you are accelerating faster at all, you will burn more fuel.
I'm a high mileage guy, long commute and ran the car for extended times with stock 215hp then three stage manifold, then stock 330ish tune and several custom tunes.
Nearly no change in my steady state fuel economy.
If you mileage is off I'd look for another cause.
BTW, you do have the disa valves connected to the correct cable?
Your car is an Automatic correct? Have you tried flashing the 330 transmission file?
