Hey Andy,
The 8683 is a stand-alone unit. You just power it and tap into a couple of
coil wires. I think it is very much worth the money, but I am also a
gadget/tinkerer type of guy. I will reach up and tweak the timing as I
drive.
You can actually feel the truck pull stronger as you advance the timing.
You'll just need to pay pretty close attention to the motor and it's sounds
if you are running more advance than stock settings. As you advance the
timing the moter becomes more suseptable to pinging, which can loosely be
described as the fuel mixture exploding, rather than burning in a controlled
manner. Prolonged severe pinging WILL ruin your engine, so you'll need to
keep that in the back of your mind at all times if you're messing with the
timing.
That said, you can feel a little more power with better gas, and advanced
timing. What that equates to in numbers I don't know... maybe 3 or 5 hp?
Also, you could just skip installing the ignition control and advance your
timing a few degrees from stock, and run premium fuel. But pay close
attention for pinging.
The convenience of adjusting for gas, load, driving style, etc. makes the
MSD box very worth it to me.
Hope this helps,
Brian.
