* Reduce Weight: This is the single biggest bang for your buck (or lack thereof) in terms of performance improvement. Remove anything unnecessary from the truck: spare tire, jack, tools, floor mats, anything in the bed. Even removing the back seats (if you don't need them) will make a noticeable difference.
* Aerodynamics (Slightly): While not a major factor on a truck, removing exterior accessories like running boards or a roof rack will marginally improve aerodynamics at higher speeds.
* Tire Pressure: Ensure your tires are inflated to the recommended pressure (check the sticker on the driver's side doorjamb). Properly inflated tires improve handling and may slightly improve acceleration.
* Maintenance Tune-Up (If Possible): This is a gray area since you're aiming for no money spent. However, *if* you already own the necessary tools and have access to spare parts (maybe from an old engine rebuild or a parts car), performing a basic tune-up – changing the air filter, spark plugs, and wires (if they're old and worn) – can make a small difference. But if you need to buy anything, it violates the "no money" rule.
* Driving Technique: This is free and crucial. Learn smooth, efficient acceleration techniques. Avoid harsh starts and unnecessary braking. Practice shifting at the optimal RPM for your engine (consult your owner's manual for recommended shift points).
Important Considerations:
* Limitations: Without spending money, the potential for significant performance gains is very limited. These are minor improvements at best.
* Safety: Don't compromise safety to save money. Never drive with worn-out tires or compromised brakes.
In short, while you can make *minor* improvements without spending any money, significant performance upgrades to your 1995 F-150 will require investment in parts and/or modifications.
