Sean is right. You might be using excessive engine power which is burning your fuel more than it should.
Below 10,000 ft, you should not exceed 250kts (approx. .37 mach). I'm sure there are some charts online that show what speed the CRJ-700 should be at certain altitudes as you climb. I see that the max for this AC is .86 mach. There are converters online such as

Does your AC come with an autothrottle (A/T) switch by chance?

Thanks for the advice -- my other half said that he'll look into the programming for me as soon as I watch Terminator 3 and Salvation with him (not a bad deal!
)... he was playing around with some free aircraft sounds last night and made a lot of our AI traffic with roaring rumbling engines now... pretty cool!
Not sure if this is anywhere close to realistic, my usual routine is as follows:
1) Take off around 160kts, depending on the a/c,
2) Climb at around 3000ft/min and at 220-230kts, usually meaning about 70-80% engine,
3) Once I pass 10000ft, I increase the autothrottle to about 290kts,
4) Back down to about 2300ft/min by FL180, keep it at about 290kts,
5) By about FL250, I reduce the climb to 1500ft/min or so, and leave it at a cruising mach.
Does that sound about right?
Thanks,
