j hancock Posted August 4, 2015 Share Posted August 4, 2015 What numbers are you getting from your boost gauge?Any leaks in the cooler or associated plumbing will kill power. 1 Quote JimIt doesn't cost anything to pay attention. Link to comment Share on other sites More sharing options...
Waterwagon Posted August 4, 2015 Author Share Posted August 4, 2015 Checked for leaks in whole turbo exhaust system. Getting between 20 and 25 psi depending on what gear. 12 and 13 will hit 27 until 1650 rpms and it will fall off to 22 Quote Link to comment Share on other sites More sharing options...

Dieselwrenches Posted August 12, 2015 Share Posted August 12, 2015 Fuel pressure?? If you've never replaced unit pumps I'd replace all six, they are known for under fueling as they wear and age. No fuel no boost. It's expensive but worth it. DO NOT REUSE OLD UNIT PUMP BOLTS AND TORQUE ACCORDINGLY. Quote Link to comment Share on other sites More sharing options...
Superpuppy1061@yahoo Posted August 30, 2015 Share Posted August 30, 2015 I've got an '06 with a 427 in it and I'm looking for someone near the Pittsburgh area to turn it up. It has no power on the hills or any help in this . Quote Link to comment Share on other sites More sharing options...
Challenger Posted August 30, 2015 Share Posted August 30, 2015 When you have a low power complaint you NEED to know your fuel and boost pressures. You'll just waste money troubleshooting without fuel and boost pressures. It would be easy to waste $3000 to finally realize you have a bad fuel filter, or cigarette butts in your fuel tank causing low fuel pressure.
