Speed limiter on '91 454 SS ?

Do the TBI engines have a speed limiter like the vortec engines?

I would bet on yes, and it would be whatever the stock tire speed rating was.
BUT ....I could be mistaken.

Nope - the top speed and HP of the engine is good enough

I'm guessing 98 MPH is the fuel cut off point that's burned into the chip like most of the rest. I've never looked at a 454SS .bin to see what they burned in it.

I have had my '88 k3500 above 110 MPH and It did not shut down. My '98 k1500 does shut down around 100 MPH.

I think the shut down for the vortec trucks 4.3 5.0 5.7 and 7.4 is 98 mph I do not know or even have a idea what it is for the diesel or the tbis that do have them

That is about what my '98 does. 98 for the '98.

I don't see where there's any speed limiter on the 7747 but, my EBL Flash-II can limit spark and fuel you can set to any value, even has a "Valet" limiter.

That is what they needed on Ferris Buellers day off.

The .bin in my '91 305 is 98 MPH with a 4800 RPM limit and the BPSA .bin in the 7427 for '95 G series van is the same. I haven't studied all the .bins on gearhead efi but the few I have looked at all had 98 MPH speed limiters. I'd be interested in seeing what they burned into a cop car prom.
If you have the ECM# and BCC for the 454SS I may be able to find it and see what they did.
