93 F150 Top Speed Limiter

[PKRWUD]

I have a '95 F150 300 / 5 spd / 3.55 LS. The speed limiter kicks in around 95 mph, but when I installed my JET chip, it got rid of it. Adding a K&N FIPK made a HUGE difference, as did the chip. I also put on an Edelbrock RPM cat-back exhaust, which helped some, but sounds better more than anything. I wouldn't waste any money on headers if I was you. If your factory exhaust is like mine, it's just fine. The dual tri-y manifolds do an excellent job! I tried different ignitions, and found the factory one to be the best (tried Crane HI-6 & MSD). I did replace the coil with a Crane PS 91.

As far as the tranny goes, check the fluid level. The Mazda 5 speeds are known for leaking the fluid out until the tranny starts to grenade. You should probably just replace/rebuild it.

What gears are in your truck now?

Take care,
