just wondering if anyone has had this issue before. my tach isnt reading right on my dt5352 i think the exact model is. 3 window digi. when i calibrate it to 1,thwe lowest i can go, the tach only reads at 10.98 or so in that area. can anyone tell me what the heck i got wrong here. temps read all good and steady. reading aroun300-350 at idle. little low i think but fat is safe for now imo. tops i have hit rippin a bit when it was cold was 1167 and 1169. thanks for any info.
