Adjusting T/O thrust

I am playing around with the posky 737 to try and give me less take off thrust as the thrust which is on there currently is almost enough to give this aircraft a STOL rating. The trouble is when I adjust the thrust scalar to give me less take off thrust it also disables the oportunity to get anywhere above 28,000ft without stalling. Is there a way I can decrease the takeoff thrust but still keep its cruise thrust as it is?
thanks

Don't use as much throttle on takeoff, say 80-90%, should save fuel too.

hmmm, yeah ok, just thought that there could be a way to make it have less power at ground level through the cfg

I'm not a jet pilot.. so I'll defer if one shows up.. I've got my hands full simming a C172 realistically.
From what I have learned.. Jets are extremely over-powered. Remember, they have to be able to sustain a climb, fully-loaded, AFTER an engine failure. For 737, that would be 1/2 the thrust gone :o
I'm pretty sure the FMS can be set to limit thrust at takeoff.. Even if you move the throttles to the firewall, you're not getting 100% thrust. And I know for certain that (load-dependent) that until they reach 10,000msl, they can be climbing out on as little as 75% thrust.
On the rare times I do fly sim-jets.. I'll firewall the throttles and then immediately bring them back to around 90%.. and then even 70% after rotation.
I have a CaptainSim 757 that DOES limit thrust to something like 75% during takeoff.

Ok thanks, what you have said makes sense in many jets I have, As many of them if you try to max out the throttles they will jump back to about 75% as you said.
Thanks for your help in the understanding of this
