New member, love this site and love my truck. Has anyone seen this problem after loading the superchips 1705? Loaded "tow performance" mode after trying all 3 modes in my 2002 F250 7.3 PSD. Normal stuff, a little smoke and wastegate flutter when hitting the pedal hard. The next morning when leaving the driveway (probably didnt let the engine warm up much), when I gave it some pedal, I heard a loud clunking, grinding sound from under the hood or somewhere and the truck stalled a little. Everything has been fine since then, except that the wastegate no longer flutters or operates no matter how hard I run it. I can manually move the vacume actuator, and the hose looks good, just seem to have lost all wastegate activity. Is this a first? Any ideas?

 

First of all do you know what the WG is and does? Do you know if its working now or not?" Cause a malfunctioning waste gate is not a good thing..too much boost and poof. Your engine should run great without the waste gate working up to a point. You don't want to over boost it. The waste gate opens to allow boost to peak at a certain PSI. I'm not to familier with the ford system they may have safegaurds. I'm curious now I'm gonna look into it.
