seems to be slower, less boost.

so, I installed my new (to me) 3 inch downpipe and cast elbow with dump pipe today and was sorely disappointed with the results. I have no leaks and it runs like it did, but less power. I still only have the factory boost guage(I know, I know) and with the inferior info it gives me, I am not boosting like I did. Any ideas?

FYI, I replaced factory DP and testpipe with the new stuff.

No boost gauge. So are we to assume there is no Scanmaster, Powerlogger, etc, that would provide info for a diagnosis??
W/o info, it's a SWAG as to what's going on.
I'd suggest that B4 you get to romping on the throttle, you get some instrumentation, tune it, and avoid driving over the crank.
