I have a 94 ford crown victoria that I just ordered a chip for(if they make one for it). The computer code is A4J2. Will the rev and speed limiters be taken off? What else can I expect with this chip?
thanks

 

Expect a noticeable increase in power and all around better driveability. I love mine on my Ranger. I seem to be getting better mileage as well, so that helps offset the price of premium. Haven't had it long enough to know exactly for sure on highway mileage, since I've only got one trip on it since swappping thermostats, but so far it seems to be getting better, especially in town, and that's with me running it hard and enjoying the extra power.

 

Yes, I can do a A4J2 with the limiters raised. I don't recommend turning the rev limiter off.
