If I might suggest a complete tune-up everything replaced after you have checked for any codes, if you have any fix those first. Then start with all new fluids from the radiator (get a new one and water pump), drain and replace differentials, trans, transfer case with new fluids. The oil and filter are a given and check and fix any oil leaks. This is where to start to gain a few HP and MPG.
Once you finish all of these then come back and we can help you with a few more but these should come first.
BTW forget about a spacer they are worthless and gain nothing.

Let's try this from a different direction.
1. What is your Hp/Tq at the wheels you are looking for? 2.How much money can you devote to this goal?
(check all that apply)
3. What is your skill level?
-A. You have rebuilt an engine N/a?
-B. You have swapped an engine N/a?
-C. You have modified a n/a engine to a F/I engine and tuned for the new hardware?

If you would like factory performance than do a leak down test on all cylinders. If readings are within normal limits you should have factory performance.

If the cat was removed then your ecu is not seeing the correct readings for the fuel mix, you should have a code from that sensor not working.
I may be missing something here but that should be an issue with performance.
Entry level lift kits cost from $4-700 depending on brand I run a Rustys 3" lift but do buy a full leaf/coil/shock/hardware pkg. not an AAL setup or spacers/blocks. You can spend a lot of money on a quality lift using all high end parts like a long arm, shocks, etc.

I'm sorry but cats are just a waste of time. I mean I was just needing some advice and everyone is making a big deal out of this day thing and throwing codes. The only code I have in my ecu is an 02 code it may not being reading the correct fuel/air mix but it runs fine doesn't effect it a bit. I'm just saying want more power. It has power it's gets decent mpg I just want more power. For the guys giving good advice thank you for the ones who ain't sorry I'm not trying to be rude.
