no power in an l76

[dynarex]

well after a boat load of tries i just cant seem to make any bottom end power on this thing-its just a pig-no traction control no torque mgmt no kr- its just a gutless slug under 3000rpm has anyone livened these things up?my tune is way better than factory and im coming from a duramax but this thng barely chirps the tires from a start is there any help other than a leafblower strapped to the intake?

What are the mixtures, I played with one that was in closed loop to 3000rpm, adding fuel down low helped.

I feel your pain dynarex. The Avalanche I'm working on wont spill a coffee sitting on the dash board from a dead stop. Maybe I'll tell the owner it has a cargo protection table that designed so that if you leave the tailgate open, nothing will fall out under acceleration, and that it cant be modified.
