I've found in the past with modified engines that if you cruise along in a high gear just brushing the throttle you will see gains as there's more torque at any given RPM once the turbo is spooling.
BUT as soon as you hit the gas the whole point of the tuning is that you're throwing more air and fuel in (or just fuel in a Diesel as they run at full throttle air induction all the time) so it's going to drink more.
