a little noisier?

i got my egr delete/oil cooler fiasco done. maybe im paranoid or haven't driven it in days but the motor seems louder then usual it just doesn't seem right. usually down the interstate its really quiet. now it sounds like a 7.3. and its not as snappy. any ideas? cruising down the interstate i have 2-3lbs of boost at 60. egt's are about 650. dont know if this isn't normal because Ive never had gauges until now.

thanks,tyler

I would double check all turbo connections. My ypipe wasn't properly aligned. It made a big difference when I got it on right.

Another thing that could have happened is that you got air in the HPO system. It will feel a little sluggish and non-responsive until that works it way out.

As far as what FordWake said, do you hear any hissing at all?

Can't help you at all there. My truck has never been on the interstate at 60 mph.

When you first started it up, how long did you let it idle? You have to complete the adaptive turbo learn process.

Not good enough. Disconnect the batteries with the lights on for 10 minutes. Reconnect the batteries then cycle the key to the on position for 10 seconds, then off for 10 seconds, then on for 10 seconds and start the truck and get out of it (so you don't touch the accelerator). Let the truck idle for a minimum of 5 minutes, 7 or 8 would be great to insure that the learn sequence is completed. Then shut the truck off, start it up and take it for a spin. The 2003's require this adaptive turbo learn procedure to complete. I haven't removed my EGR cooler or valve, so I don't know what impact that may have for you, but to be on the safe side, make sure your egr valve is plugged in.

This may or may not help you, but it is required when the KAM is cleared on 2003's

Oh, and retighten the clamps on the turbo that may help with the sound.

Oh, one final note the engine oil temperature has to be greater than 150, so don't do it on a cold truck.
