Hey guys what good power upgrades are out on the market.
That you have on your jeeps that work well

I have the following :
1. Cold air intake
2. Hypertec computer flash
3. 2.50 exhaust system
4. Live wire ( coil , wires )
5. Throttle body spacer.

It's just not enough though.
Any ideas besides dropping in a HEMI
 

Does any of that make a notable difference?
