currently I do not, my tuner Mike who runs a speed shop in Rochester, told me about the false knock using HPTuners and he was hooked up to a wideband but I haven't gotten the guts to go ahead and buy HPtuners with a wideband for myself yet, I need to read up a little more on everything before I do since a lot of that is foreign to me. I did change to larger 28.8# injectors for the Dyno pulls and he said he mapped the computer for those first, he said it might be crap gas remnants of fuel injector cleaner/octane boost that might be in the tank.
I did hook it up to a handheld OBD2 scanner my mechanic friend has and we went for a drive and he said everything appeared to be fine regarding the timing being retarded by the computer, it only pulled 3* at most and it was all between shifts so it may be taken care of now, I just wish I knew for sure, I need to strap her down to a dyno again and find out come spring.
