>> Dear Sir,
>>
>> We do not recommend using platinum tip plugs with the MSD unit, we also
>> recommend gaping the plugs to .050 to .055 to obtain maximum air/fuel
>> mixture burn. The platinum plugs have a tendency to run hot and can
cause
>> detonation. If you have your old plugs or pick up a standard none hype
>> plug one step colder and see if that helps. if the plug gets hot enough
>> and starts causing some preignition and the computer picks that up it
will
>> retard the timing which can cause the poor mileage. Reset the computer
and
>> take the truck out and drive it normally. This will cause the computer
to
>> relearn with the MSD box in place and help over all. On the O2 Sensor, it
>> is only affected when you are under a load condition or full
acceleration,
>> with light load or cruising it should not add anymore fuel, it is
striving
>> for 14.7:1 air fuel ratio.
>> Thanks,

>> Member Answers:
>> (1) Are you supposed to run platinum plugs with MSD?
>>
>> (2) Your spark box/wires/plugs helps to burn the mixture BETTER. so
>> there's
>> less
>> oxygen left for the O2 sensors. Computer thinks less oxygen content in
the
>> exhaust which means it's too lean and it enriches the mixture by opening
>> the
>> injectors more. Therefore you're using more gas.
>>
>> (3) I hope you remembered to gap the plugs at .050. That makes a big
>> difference.
>>
>> (4) Reset the computer
>>
>> I personally also run the 6470 w/8207 Coil, Splitfire Wires/Plugs (Gapped
>> @
>> .050") and haven't had anything but great success.

>> Your help would be greatly appreciated...
