Performance chips
My research on www.Rangeforum seemed to indicate the most popular performance chip for the 4.0 SOHC Ranger is the "superchip". Is any one out there able to comment on this ? Will it deactivate the speed limiter? Who sells it ? Any info appreciated.

I bought mine from motorhaven.autoanything.com last year for $175. I believe the normal price is $225.

Yes. Can get away with 91. I went a step further & tuned my Inlet Air Temperature sensor (IAT) to optimize the fuel. Used a 10K resistor in line at the harness. Also, relocated it to the front of the rad supoort to take in a colder air signal. Works great!!!
