stacking the evo and the 10K will not cuase any problems you will just have to watch EGTs very close. to get a quicker spool up either disable the waistgate or adjust the waistgate actuator to open under more boost. if the gate is disabled keep an eye on your boost with the evo and 10K you will hit 25 or 30 lbs easy and this is hard on the turbo bearings.
