i had a cai in my truck but couldnt get rid of the droning with timing. bill sent me a pm a while ago weeks before sema and said my recalibrated custom tunes were done. i tried to dl them and i got an 87, 87, 91 tune. i ordered an 89, 89, 91. im certain these are not my tunes. i also noticed that in 91 perf mode i get a vibration upon hard acceleration. no other modes does this. i remember when i first got my gryphon the 87 tow did this.
two questions:
1) are they around much? still waiting for my updated tunes.
2) is there any else getting this wierd vibration on any of their tunes?
