LC' s...it's all about the engine/drivetrain
torque.
That is the LC's strength. It has low final drive gearing.
As above posted ...take out of OD ..use ECT. Then if needed drop to next lower gear.
Yu will surely pull a house down!
You can not make a
Rocket Ship out of a
Tractor.
Not the
carefully intended design of this vehicle.
Playing with the intake alone (CAI, etc.) will yield little HP.
Little cost benefit.
I would drop in a
K&N air filter or a
TRD version at best for approx $40.00, if yu haven't already, And see what happens.
At least they are washable/reusable for life of vehicle. That IS a cost/benefit by itself. If not for added breathing with a
possible 5HP gain.( not much) But it might
work for yu.
Just my ideas.
