Forced Induction no one to talk to

So first of all I did not drive the car much while we were trying to figure out what was going on. I didn't want to cause any damage if the intermittent detonation, pinging or what ever you want to call it was real. The pinging would only happen on the freeway after about 15-20 minutes of driving at 2500 rpm. It would not come on any other time. (low constant RPM) The pinging would just all of a sudden start. I quit driving in 6th gear and kept the RPM up to 3000 in 5th where the pinging would never start no matter how long I drove. I also rarely boosted the FI. If pinging started, I would pull over immediately, turn the car off then restart. The pinging would stop and I would continue on. The uprev tuner said that there are other issues that may have sounded like detonation but not "real detonation". So I don't know if damage was done or not. I'm guessing the reflash to stock happened a week before I bought the car. The car was not being driven at the time so, I think the issue started with me. Other than the pinging, the idle was rough and irratic, the throttle was not real smooth. It seemed as though the boost gage sequence was not as smooth. The car did get up and go if you wanted it to.
