Is it just me or does the 95 have a rev limiter, and does the chip change, change this. I think mine cuts out at about 4800 rpm. Never seems like enough in first gear.

4800 RPM? I barely ever hit 4K on mine (on purpose anyway). You're just wasting gas and risking harm at that engine speed IMHO. These engines aren't designed to be high revving. But in any case, I've been told they do have rev limiters, and yes, it sounds like you are hitting it, and no, I don't think the chip will fix that.

???? Rover V8s love high revs. They should be good to 6000 rpm. 4000 rpm is nothing. Can sit there all day long.

Yes that is the rev limiter ( mine starts to miss at 4800 rpms also) and RPI chips will give you a little extra room there if you use their chips. They claim! I don't know about the other chips out there.

What they are doing is something like increasing the air and fuel to the engine which will give you 5-10% more horsepower therefore you don't need to rev as high. But I for one would not want the rev limiter disabled. They also claim to do away with the speed limiter. If you have aftermarket exhaust and a high flow air fliter then you may notice the difference. The ECU in these vehicles will not allow the engine to use the extra airflow gained by the upgrades and the chip will reprogram this. This is what I have found out thus far. If I am wrong (very possibly) someone correct me.

How about 95? and what year Disco we're talking here?
