A319 Performance issues

I recently downloaded a PAirbus A319 from a virtual airline but have noticed some slightly off performance numbers.

Even with my engines derated, by the FMC, I am taking off in about the distance it takes a piper cub. I think the VA altered the original engine static thrust and thrust scalar numbers in the .aircraft cfg but I'm not sure. Can anyone supply me with the actual thrust ratings you guys used for performance?

I think these guys expected to be do 2000+ft/min at FL360 at .78 mach.....

Thanks -

Chris

One more question along these lines

When on the ground at about 25% N1 the aircraft will accelerate (if i'm not paying attention) to about 60 knots. Is there a way to reduce the amount of thrust that the engine produces on the ground without changing what it does in flight? I seem to burn about 2500lbs/hr per engine with this current .air file.

Don't think so.

Perhaps someone knowledgeable enough can edit the N1/thrust ratios for 0 mach in Table 1506 of the .air file?

I am certainly looking to fix idle thrust and required friction break away thrust as well on the ground. The only thing, I think, currently wrong with engine performance.
