need help with gas mileage

[Ssiptang]

I actually expected a large decrease in MPG when I added my cams/headers/o/r X/ JLT but only lost about 1 the first tank, and thats with me driving hard.

Don't get me wrong, I'd love better MPG, but thats not why I bought this car, thats what my TDI is for, 48mpg @ 80mph FTW!

Did you gain any mpg with UDP?

I understand modified Mustangs don't get the greatest gas mileage, but surely mine can do better.

the udp, cmdp, steeda intake, tune and borla stingers (and suspension/brakes) were all added as a package from barber driving experience.

I cant comment on the MPG change, sorry.
