Turbo boot cover

Hi all,
I have an Ď05 Holiday Rambler Navigator 43 PBQ. A little over a year ago I blew the turbo boot cover on a mountain pass. Itís all back together but hereís my question for the group: once parts have been replaced is there a code that needs to be reset? It seems I donít have the same old power going up hills. A few weeks ago I was going over the Grapevine here in CA, a 4,000 foot pass, and I was in second gear doing 29 mph so my boost gage wouldnít be pegged.
Anyone have experience with this? Any input would be appreciated!

Restricted/diminished fuel flow will also drop top boost. Focus on turbo, waste gate CAC. and boots and air cleaner, but not blind eye to another cause. Don't ignore exhaust brake not fully opening.

Maybe I have something to learn, but what is a turbo boot cover? I've never heard of such a thing. Are you talking about a turbo hose rubber connection? If you blew a hose on the charge air cooler, the new one may not be installed correctly and is leaking.

If you waited a year to drive the coach again, it could be a fuel issue as mentioned above. Have the filters been changed lately?
