Out of tune?

I recently had a short section (approximately 2 inches) added on to a 3/4 King BBb tuba immediately before the leadpipe. I did this to position the mouthpiece at 90 degrees to the instrument.

Can anyone explain why the tuba is now so flat that even with all slides all the way in I can't quite get it in tune? Before the addition, I had 3 slides pulled out a total of more than 5 inches combined.

Short of having the work "undone" does anyone have suggestions?

Thanks in advance.
