Mechanical or HPTuners issue ??
418in ls3 TH400
Car has been running great. No issues at all..
Approx. 1 month ago the car stopped reading the commanded Timing table
and will run at 29* at WOT no matter what numbers I have it commanded at.
Curious if anyone has ever run in to this issue.
Could it be a cam position sensor ?? Speed Sensor or something screwy with HPTuners ??
