turbo relearn

How long does it take for turbo to relearn after it has been off for 4 days?

If you haven't reprogrammed it (only had batteries disconnected) I would say that the relearn time is zero.

My turbo sounds a little funny. Still pulling my trailer but sounds different. My exhaust was blocked off long ago from the egr cooler, I also gutted the cat. I could here a little whisle out of the tail pipe. Now I don't here it. And I here like a exhaust leak or hissing but I don't smell any thing in the cab. Could the turbo stuck just in 4 days?

If you had the turbo out too you might not have gotten the y-pipe to turbo flange lined up right. I spent a whole day, literally, working to get one matched back up. If that's where it's leaking--you can feel it with your hand or see smoke--try loosening the y-pipe at the exhaust manifolds and lining up at the back of the turbo first then go back to the manifolds. I bet that's where your hissing is coming from. Did you also add a new up-pipe to the y-pipe??

OK I'll try that. No I didn't put a new up-pipe on, I had my old one are block off so I didn't see the point of changing it. But wouldn't I smell exhaust in the cab?
