I am having what i think are tuning issues with my truck. I am still on stock turbo and injectors but i have added batmowheel and ported the turbine housing. I just re-tuned my maf sensor settings as i made up new intake and the readings were off but now that is resolved.
My issue is that at cruising speed which is between 100kmh and 115kmh, i am getting between 10 and 12 psi of boost. The rpm's is between 1750 and 1900.
I had the turbo apart to port turbine and this means i had vanes and vane locator ring out also. I didn't remove the sensor or actuator but i remember that i did move the actuator arm a few times. Could my vane position not be at original "zero" position with the arm being moved? I have no tuning changes or mechanical changes other than maf and turbo work.
Say the vanes are not at true "zero" position, this could be the cause of my higher than normal boost which and this is purely assumption, that there is a fueling table based off map pressure which would explain my crappy current fuel consumption.
Any ideas or suggestions?
