Number one is pull codes and get all passed, 11 or 111 whichever your system shows.

Mine is as peppy as I need. If you want to drag race, a 5,500 pound rig it may not be the best choice. Mine will hold in OD pulling trailer and not drop but 3 mph with cruise on the hills but, I usually am nice to it and not suck as much gas with the cruise off. I just "shoot the hills."

The three best improvements on mine have been all new vacuum hoses, oxygen sensor, and rebuilt PCM. It probably has 15-20 per cent more power than 40K miles ago. Other replacements have been ECM. ACT, ICM, Distributor stator, TPS, all Mototcraft. Ford racing 9MM wires, cap rotor, NKG v-groove copper plugs, MSD? can't remember popular brand red coil. timing chain set and staying with 10W-30 (not 40) oil. K&N drop in air cleaner. Running 11 bdtc timing.

Then see if you want to spend money on more flow.

Thanks for all the help, I ended up doing RAM air and holding off on turbo or supercharging. But, I've run into a problem. Lately, after around 6 minutes of driving my bronco starts getting way too hot. After I parked the other day I popped the hood to see if I had a radiator leak or something and I felt the radiator hose to see if there was pressure and there was none and it was burning hot. Also, at the radiator end of the hose there is a hissing at the clamp, which I've re adjusted several times now. Any ideas as to what this might be?

Thermostat is stuck closed. Replace it and the upper radiator hose if the leak/hiss cannot be fixed otherwise.

that makes a difference, in putting you on a good path.
