I bought a piggy back upgrade for my 1992 sc400. it does have a slight hesitation but when I give it gas it seem to push thru it. I just installed an intake and cut the center resenator to a straight pipe. I'm getting the piggy back installed and tuned in two weeks. Should that help the hesitation. and how much hp can I expect to gain? I think its an AEM pigbak upgrade, I can't remember the name..any comments would be appreciated

Unfortunately a tune isn't going to solve your problem. You'll have to find out what's wrong with it, especially with your upgrades since they aren't massively changing anything, you shouldn't have any issues with it hesitating

so should I wait til I have the piggy back installed and tuned before trying to pin down the hesitation issue. I have the piggy back but they cant get to it until Tue. 2 wks.
