Turbo charged engine can burn more fuel, so the TD pump should have a greater fuel delivery.

Mechanical pumps can be turned up with a 5/32" allen if you can get to it.

So the turbo and NA pump are different part numbers?What determines amount of fuel to injectors on these electronic pumps?Can the pumps be adjusted for less fuel amount\duration using resistors on the sensors(baro,coolant temp,air temp sensors)?Thanks.

Put a Stiffer spring on your injection pump throttle return spring will help your fuel economy. Makes it harder to mash and you'll let off sooner.
