Driveability Issues

[mk6gtracer]

I'm very new to this, so bear with me. I'm running a former ASA Latemodel engine. Bigger injectors and a Cam. I'm running MAFless using one of EFI Lives custom Op systems 02020005. The engine generaly runs fine, but I do have a couple of driveability issues, Specifically, it wants to stall when I coast to a stop. Blipping the throttle keeps it running and it then idles fine. Also at slow speed, ie around 1100-1200 rpm in first gear it really surges. Note, due to the fact that its a midengine application using a Porsche transaxle,I do not have a VSS signal going to the PCM. I've attached my tune file. Any help would be greatly appreciated.
Thanks

I would highly recommend setting up some sort of speed sensor, whether it be from the gear box, drive shaft or wheel speed it will allow your throttle follower and cracker to operate and will help immensely.
