After about 6 months of going through couple different tranny companies I find out that everyone seems to think with the cam I have or 600 plus lift cams rather tend to make too much vibration and cause a slight rattling in my brand new T56 Magnum... anyways long story short I have been attempting to smooth my idol out a bit not to mention being the first time using hptuners it's a little more difficult than I anticipated my tune is very good no KR at all throughout the whole RPM range but my idle sounds a little blurbly and Shakes the hell out of the car and everything else I raise my idle from 800 to 9:50 and I started adjusting some air flow tables it seem to get better but I think it can actually get even better than what I can get it anyways any help or suggestions would be greatly appreciated I do have logs and I do have my HPT file ... thanks for anyone who takes the time to reply
