First off, is the check engine light on? Do you have any codes? Then we'll take it from there.

Boost leak.

Are you running a stock BOV or one that dumps to atmosphere?

If your normal idle is OK then its probably your Dashpot incorrectly set or running too rich.

Check it here and go to page EC-8
http://www.turboninjas.com/mk3supra/...ndiv/06_EC.pdf
When you decelerate, its supposed to partially open the throttle more than at idle to get a complete burn. If for example it isn't working at all you could a too rich situation that might bog it down. Just set it to factory specs and see how it goes.
