Did a search but couldn't find a definitive answer, does the Predator adjust your boost to achieve HP? I can't seem to "turn mine down", showing 21 on the gauge and want it back to the stock 16-17. I keep getting Wastegate, Turbo and High Manifold Pressure error codes.....Sherm

With more Fuel pressure the turbo boost pressure does increase. What crom are you on?

Crom?? Ser.# of unit is d007248 , Part # u7170 and Ver is v.9r04 . When the tune is uninstalled and I put the settings back to factory I get zero error codes so there's something going on with the tune. Sherm

You need a boost fooler.I put one on mine and it got rid of the codes.It keeps the computer from seeing over 20 to 21 psi of boost pressure.I am hitting 30 to 32psi boost with no codes.I have the reg.return system and I am running 68psi on fuel vs 55ish aswell.
