[s-cars] stumble at 6500rpm

[Calvin & Diana Craig]

Could be as simple as a tach. issue.  There have been many tachs go bad in
this car type.  If you don't hit at about 3k rpms at 70 mph your tach. is
off.  Truthfully, the only gauges in the S-Cars that I have not seen
problems with is the voltmeter, for those of you in the later cars, and the
speedo.

Hi!

Stock or chipped car? What altitude? You might have hit the maximum allowed
air flow limit, though 6000 would seem a better cut-off point rather than
6500, according to the original programming. Might be a spark plug issue as
well...
