A tune will cost more than $1000 when you factor in the cost of a tunable ECU (generally Hondata S300).
But that's beside the point, if you are positive your engine is underperforming compared to before then something could be wrong. -and tuning doesn't fix problems with a stock car.
If you're 100% sure it's not just that you are getting used to the cars performance and it really is losing power I recommend locating/diagnosing the issue before buying any more performance parts.
Run a compression test, make sure all the cylinders are producing similar pressure. Check for exhaust leaks (this can rob you of power). Have you bottomed out and mashed the underside of your xforce header?
Is your air filter on your CAI located in the bumper/guard? When was the last time it was cleaned/replaced or how long has the CAI been installed?
These are just a few generally easy things to turn your attention to for a start.
Regarding your fuel system, you still have a stock engine so there's really not any point upgrading the fuel system. The stock system will be sufficient. You might see a tiny increase in performance if you run some really good injectors/FPR/pump with a tune but this is way outside your budget.
With your $1000 budget you might consider picking up a second hand DC2R gearbox. Having short ratios and an LSD will give you far better performance than anything you can bolt on to the engine in that price range.
