Default Rev. limiter

OK guys, maybe a dumb question, but I took my car to 7,600 RPM yesterday and did not hit the rev. limiter. So, other than it having a different chip in it is there any other reason/s for this. Sure wish a knew the cars history better !
Thanks in advance, Bob

Tach could be off a few hundred, I think Marc set my chip at 7400. maybe you can find someone with a scanner to double check it.

If the tach is off, and it probably is unless the limiter has been boosted, calibrating it is not difficult for anyone with a little experience with soldering on PC boards.

(Note: The procedure abounds, but if you find you need it, let me know and I can PM you, or maybe it should be made a "sticky" on this web page!)

My tach is off by 1000 up there, but looks cool when you are shifting at 8000 RPM. I have a axillary tach mounted.

That's why I have a shift lite.

Mine is only off by 200 rpm or so over 7000 indicated rpm. My limiter is set 100 rpm past stock so about 7200. I think it displays close to 7400 when it cuts so no need to take the gauges apart to fine tune the resistances, but mostly I go by sound and pull the shift when the needle is at about 7k on my gauge.

Dyno is the master, but try this Marc tip, Engine speed displayed in HVAC LCD panel, press fan up and down buttons together until -00 shows, then fan up until -06, then press fan icon, display 3 digit #( mine was 155 ) x 25( mine was 3875) to equal RPM, do this at 4K RPM, mine off only 125
