I was thinking about getting the diablosport tuner for my 2001, but i dont know the specifics, like what it all does, and how easy it is to install. I also wanted to know would it be worth it to get new spark plug wires. I thought the 5 hp gain they said you could get out of them was questionable, if not, then i will buy them

Easy to use. Completely foolproof. Even RedAss could use one.
As far as plugs wires, if there's nothing wrong with your present set, no real need to replace them. It's true, performance wires have less resistance, but not so you could notice any gains, if any...

 

Only time I say you should get the wires is when you have to change your spark plugs, because I noticed that Ford OEM wires are hard as hell to remove from the plugs, and I actually broke two of my wires and one plug when changing them on my old sixer. Get the aftermarket wires because they are better than stock, but no need just to run them out and get them just to be buying them.

 

LMAO for some reason i find that first line absolutely hilarious.
