stuttering

I have a 99 psd, and after getting on the throttle a bit then letting off it seems to stutter, s if its nit getting enough fuel. Any ideas on what it is? It got better when I switched tuners

So heavy accel then no throttle at all does this?

Could be many things. Drive shaft or components all of a sudden not being torqued
