SMS B77L Engine Problem

G'day all, I've just begun using the Simmers Sky Boeing B777-200LR. I've had the aircraft on my system for some time but never really flew her properly. One thing I have noticed compared to the B77W is the difference in engine power. Now, both aircraft are fitted with GE90s but the B77W is a GE90-115BL1 (115,540 lbs of thrust) and the B77L is a GE90-110B1L (110,760 lbs of thrust). When I was executing my approach I noticed to keep the B77L at landing speed I required almost 70% N1, with the B77W it would be more around 40%. Not to mention it almost took the full length on Dubai's RWY 30L to stop her with A.B 2. So, there's also an issue with the Reverse Thrust side of things as well. So I did a little more digging and found that the B77L would produce 105.90% N1 whereas the B77W on the other hand would produce 115.90% N1. (Note this is simulator data not real-world). Data was found by just pushing the throttles on my quadrant to the full position and waiting for the N1 to stabilize. I also checked the aircrafts parameters in the aircraft.cfg to see if the engines had been de-rated in the config but both the B77L and the B77W have identical engine data and Turbine Information fields. So I'm out of ideas on how to fix this issue. If anyone could please assist me in resolving this problem is would be much appreciated. Thanks in advanced, Cheers, EK433B77W!
