TJ Performance Upgrade?

I've got a '99 TJ 4.0 with the following mods:
-AEM air intake with throttle body spacer
-Banks cat back exhaust & header
-DUI firepower ignition kit with screamin demon coil
-Jet Stage 1 performance module

It runs much better now, winds up more smoothly. What are recommendations for further enhancing engine performance without breaking the bank?

you're the victim of believing the typical corporate BS. you've wasted over $1000 on crap. yup, sorry to tell you.

Should have put that toward a $2800 4.7L Golen Stroker, and we wouldn't be having this discussion.

A Golen Stroker is your next step, everything you've done so far helped just a little bit, but the good news is it will all help a lot more after you swap a stroker in.

It looks like your running 3.07 gears with 31" tires with a 5 speed manual trans.

If you plan on sticking with 31's then it wouldn't hurt to throw in some 4.10 gears.

You can also have your throttle body bored out to 63mm but it wont do very much unless you stroke the motor.

Where are you finding a $2,300 4.7L Golen Stroker?

Do you mean a 4.7L Titan stroker for $2,495.00?

It's actually $2,845.00 with the $350 core deposit.

An axle gearing change would have been a Far better investment.
