Well I can assure you that drop off in speed will disappear with the kit. I would go D01-PRE-DO2 post on both vehicles and use a good sized tank 3L to 4L. Or you could mount something larger in the rear cargo area. I prefer trunk mounting the kit when ever I can, Keeps the pump out of the elements.

Your Bighorn can easily match that power and you will not get the lost of top end due to hill or load. And you EGTs will stall well under 1250F at all times. As well as lower engine operating temps. When I decided to introduce this there its because it's my second home and I have ridden in so many of my friends vehicles and wondered how they could be happy with that meager performance they were getting out of the motor.

We'll be back 24-26 of May for another dyno day. I'll see if I can't get our bighorn on the dyno this week to see what she is putting down in power to give you some hard numbers.

And when you quote factory horsepower and Torque ratings thats to the crank, you vehicle puts down about 17% less than that to the wheels

If the MPV we dyno'd with the 2.5L non intercooled engine was rated by factory hp/tq numbers it would be.
Mazda MPV(138hp/257lbstq)
VS
Bighorn (approx.123hp/202tq)
VS
Landcruiser (approx.162hp/267tq)

Due to the weight of the MPV vs the Landcruiser he will out perform you everytime.
