Talking about fuel upgrade? Can't help you there other than you may be upgrading fuel only to run rich. Talking about air upgrade? The 2.5L gets enough air, upgrades on a stock, naturally aspirated engine are a waste.

Many Jeepers, including myself, have found that the Jeep engines work best in 100% stock form (when they are naturally aspirated, non-stroked engines). Stock plugs, air, computer. The only upgrade I've heard good things about is the Bosch 4-hole injectors which are not relevant to your case.
