As I am pulling up a hill, I can start to hear an "air-leaking" sound on the drivers side under the hood and the truck starts to lose speed (same side as cold air intake). If I stab the throttle to cause a downshift (up to 3200 rpm), the truck speeds up, the air-rushing noise is gone, and we truck up the hill. When the truck upshifts to high gear, the wate gate releases. If I keep my foot in the throttle, I can keep the air-rushing noise going, and start the whole process all over again.
There are a lot of variables at play, but yes. When the turbo is surging, the motor is getting inconsistent superheated air. This is a bad thing on multiple fronts. Tuning also is key in controlling surge.If the surge is fixed, will it help raise the mpg? Is is there something else lowering the mpg, or is the surge killing it all by itself?
A WW is simply the OBS style wheel. It may help stop surge on occasion, but it is not capable moving as much air as the SD wheel, so it's actually a step backwards. A ported housing has shown to resolve the issue most of the time, but now we've spent over half of what one can find a used 38r for.Would a wicked wheel stop the surge?
How about a wicked wheel and a better tune? I want 14 mpg towing or I'm moving on to another platform.
Would that restore the mileage I'm looking for?
