Heres the problem...
Drive the car from cold goes really well as the engine warms up power (torque) seems to decrease significantly.
Car has been superchipped with turbo pressure at 14psi complete scorpion exhaust including de cat pipe.
Anybody with any ideas????
I am suspecting the actuator?? or maybe the lambda sensor (or though the ecu light does not come on).
This is getting irriatating!!
