Let me venture to guess that what you are experiencing is the typical stock un-modified Porsche 930 low compression engine and old 3LDZ stock turbo. Completely stock, the 930 is a dog off the line and only really turns on...and violently...above 4000 rpms as the turbo finally builds boost. It's the nature of the beast. These cars were not meant to be fast off the line for drag races, but will kick some serious butt on a rolling start. How does it do in 2nd gear, say about 3000 rpms and you stomp the accelerator to the floor? In about 2 seconds it should launch you to full boost and 70 mph at least.

Want more or different performance? Lots of things can be done with simple bolt-on stuff....and a little $cash$.
