Yes, I was exaggerating... a little bit...if the Toyota is rated at 300hp, it's probably down to around 160-170hp near the peak and you will notice it.
381 hp at sea level is 255 hp at 11,000 ft. The Tundra 5.7 is certainly not lacking in power up to and beyond its payload and towing ratings, even at extreme elevation.
A stock 7.3 will make about 235 hp at any altitude because of the turbo.
Now add just a $375 PHP Hydra tuner chip with 16 different tunes and let's say use the 80 hp tune.......
You end up with 315 hp and 650 tq.
With the toyo you have stock 381 hp and 401 tq.
At altitude, 255 hp and 268 tq.
BTW it is important to me to go up a big nasty hill at speed.
I don't want to go up a 65 mph hill at 35-40 mph while holding everyone up, not to mention at speed you have plenty of airflow for your Trans cooler, radiator , intercooler, and AC. When you just creep up the hill, your torque converter will unlock in 2nd gear and heat up the trans, and your fan (if mechanical) will kick on dragging another 20-35 hp to keep everything cool enough due to low speed.
