I'm Awesome
For those of you who might be interested I had my stock 454 on a chassis dyno today
1997 7.4 Vortech
The tuner said that it would be lean........and he was correct....so lean it was scary and you can easily pick up 60 hp with putting some fuel in the engine.
15.1 AFR
290 Ft pounds of torque at 3000 rpm
200 HP at 4200 rpm
so flywheel numbers would be:
340 Ft pounds of Torque
240 Horsepower
So it feels real bad when towing and now I know why
The problem is you cannot do much about it except send your box to blackbear and then put it back on the dyno to see what they did if anything.........start with wide open on a load throttle of 12.5 to 1
not 15.1
You could do a 0411 swap but it seems like "Lextech" is unreachable and even offering money does not work. I would love to purchase the printout but no response along with many other guys.
