I have installed the dsp5 in my lb7 and everything works. My problem is that my performance tunes drains the rails or pops the relief valve and the engine falls on its face at the end of second gear if I take off from a dead stop. It runs fine if you get going and roll into it. I used fuel,timing,base torque tables from my known good tunes from the stock operating system that work without any problems at all.
Is there something I need to be doing different working with the dsp system?
