Other than gears what can be done to help performance?

[ProjectAviator]

I am wondering what can be done to increase performance? I lost performance when I upped my tires to 32s. It does pretty good off road but struggles on the highway. It is a 95 XLT 4.0 auto with LS 3.73s I really don't want to do gears right now.

What can be done, Tcase mods, engine mods Etc.

You could look into freeing up some of the power you already have by using an E-fan and some pulley's? I've done both and I can tell you that you will feel the difference. Don't expect a miralce but it's worth it IMO.

You don't want to hear this, but with your drivetrain and relatively weak tranny, adding power to it won't really help much. Larger tires change your effective gear ratio- straining things. Regearing to 4.10 will take some of the strain off of your motor and trans, restoring performance and prolonging the life of your transmission.

If you are dead set against regearing, with your exhaust and intake mods, I don't really know what else you could do.
