Pops and bangs uses more fuel??
My car was mapped by SC a year ago, and when they did it they managed to make it pop and bangs (not at my request) I must admit i do like it sometimes 
I tend to need to fill up weekly, and I don't really do alot of mileage, I'm just wondering by the way my car was mapped, could that be why I need to fill up more often, or cos I have more power???

As factory your car stops injecting fuel when you lift off the throttle, or coast down hill in gear etc.
Its called overrun shut-off. Its something EFi equipped cars have had since the early 1980's.
"Pops an' Bangs - innit" basically disables that fuel saving feature...so when you lift off the throttle or go down hills, fuel is still being pumped into the engine. The mapper just tweeks the ignition timing so it ignites it in the exhaust....hence the bangs.
In efficiency terms, its essentially like going back to using carburettors to fuel the engine.
So yes, its wasteful on fuel.

When we map in pops and bangs the driver has to slightly breath on the throttle pedal on over run to get the car to do it, not all the time so you do get to decide. is your foot totally off the accelerator pedal when you are getting bangs and pops?

Mine used to go mad when coming off the motorway...(Mapped in by Duncan) and normal overrun pops and bangs the rest of the time...
When I got him to remove the pops and bangs again (was a tad immature
) the car felt quite boring
And the mpg didn't change one bit

A friend of mine had pops and bangs added via PFC commander and with fitting a o2 sensor and knocking pops and bangs off, he moved from 220 miles per tank to 260 miles per tank. similar driving, same routes.
That o2 sensor will be paid for in no time
