Default Best engine performance mods

What are the best performance mods to put on for more power in order from which ones to get first.
Have 2010 rubicon 4dr 37s with 513 gears.

1). HEMI


Then there's no need for a number 2.

x2.

But if budget does not allow:

2. RIPP Supercharger

3. PCM Progammer when available for '10

4. Free flow Exhaust

5. CAI, if noise gives you the sense of power

6. TBS if you like whistling

7. Smaller tires

My first mod!

Again, FlashPaq will be good. I plan on saving up for one soon.

if i was to do anything i would just get a progamer. and maybe re gear like others posted. i have done all that other crap on other vehicles and i think its a wast of money i never really seen a difference at the pedal. save your money and go for a hemi or RIP charger. that will most likely be your most bang for the buck.

For less:

Unfortunately, if you have an automatic, you wasted money by not going with 5.38 gears. If you have an automatic, it will eventually be worth the $1k to regear again to 5.38s.

Very true

Questions welcome- but a search reading - just installed my RIPP supercharger - will really help.

1. engine swap
2. Ripp supercharger
3. gears
4. programmer

IMO everything else costs too much and brings little increase in performance.
