110 mph cut off

[turbokar87]

Quick question...
In my 87 GN when I hit 110-120 mph the car shuts off.. Iv searched how to get rid of it and didn't find anything.. Maybe I'm phrasing it wrong.. But what can I do to to stop this from happening?

most aftermarket chips remove the factory speed limiter.

what chip are you running?

The stock suspension is not really stable at those speeds, so be sure you plan upgrades for that.

"110 -120 "..which is it ?
.. sounds like a line from mr mom


need to know what chip, injectors , rest of combo
either way my advice is get a new chip from one of the vendors as the fuel cut limiter will be eliminated or raised
stock chip had a 125mph fuel cut off

All stock.. Speedo only goes to 85 so I'm not sure going according to what my gps is telling me.. Nothing done to the car. Just a intake and exhaust. Where can I get a chip to program it?

Sounds like you need to pick up a Scanmaster to monitor what's going on & to see a more accurate MPH reading.

Might as well buy a Turbo Tweek chip & the required fuel pressure regulator while your at it.
