Turbo BACKPRESURE to BOOST Ratio!!! Are you monitoring it????




If not, you should be!!! Backpressure is a natural byproduct of the turbine wheel doing work spinning the compressor wheel! But if the turbine wheel is too small, cam is wrong design or you have a less efficient exhaust system, you could have way more backpressure than boost pressure!
