if you had a large set of injectors and a ran on valet would you be able to get pretty good mileage and decent power because of the way low rack travel?

I have a PDR switch, which uses a pack brake valve. They are all the same concept. I run a #100

What exactly do you want to know?

My injectors aren't that big but it seems to work for me. Although even with my pre-boost screw all the way out I can still get 25psi and 1100* unloaded in valet

What kind of fuel mileage improvement are you seeing? I'm considering buying the PDR switch sometime soon.

If I keep it on I usually see a 1-2mpg gain around town, but on the highway its the same, since I don't keep my foot in it on long trips. Its only a limiter, if you don't go over 1/2 throttle anyway you'll see no difference. I think with a stock setup truck valet

good info. well i guess i'm trying to keep my stock injectors, but will that effect power gain. i'm looking for an aide in power when towing large loads on inclines. i havn't heard any personal accounts until now. i spoke with an ATS tech but he was no help.

not sure I understand the question...... A valet swith cuts fuel and limits power. When not in valet, the truck runs just like normal. The switch setup has no relation to the plate or max power of the truck.

im wondering if i ran no plate and a valet with 5x.016 injectors could i spool a garrett 64.5mm to around 25psi and keep pretty good mileage.
