Knock sensor is working over time in your case taking out timing when you really needed. Hence, sluggish throttle response.

Which software are you running WinALDL, Tuner-PRO?? Can you capture data logs? I wonder what your cross counts look like and BLM's - my guess they are all well above 128-132 region.

I'll order a more professional one, it is a Mr. Gasket gauge i believe and i just got it at the time cuz it was there at oreillys. I would definitely agree that it seems like it does not advance the timing properly ( oh yeah the reman distributor has a new module on it too). I've just been using Tuner Pro so far but not really familiar with it yet, just happy i could see my basic live data so far. Cross counts would go up so far and then start over and my BLM's I will have to check it tomorrow. If you know how to use the program and can tell me what to do to record or anything else useful i would appreciate it!
