Easy, switch out the 4.56 gears with locker to a 3.92 rear. That will simply give your vehicle more peep performance by getting the wheels to turn more frequently. The 4.56 rear gearing sounds like your truck belongs in a mud pit at a tractor pull vs. jumping on it at a light to smoke the tires by rocking and rolling.

I would not go with the Holley mod if your engine is a Magnum type. Why go backwards in fuel technology and performance?

High flow CAT is a good choice. Do that too. The engine really breathes freely for upping the power.

Use Valvoline's PowerSyn synthetic grease for all the wheel bearings. It has a good amount of Molly in it and exceeds our grease bearing specs. mot only will the power move your truck, but it will move it more freely. PLUS, the other benefit is better MPG !!! A double hitter here in my book.

Redline 75W90 synthetic rear gear fluid with friction modifier is a big help. It's really formulated for the Chrysler rear ends. It exceeds the Chrysler TSB requirements for our trucks.

Ding the TB intake mod by doing the grind and polish. This really helps the air to flow into the engine better. Whith a high flow CAT and exhaust, you WILL NOTICE a difference.

Simply stated ... side-gap the Auotlite platinum plugs.

Since your 5.2L is a 1998, clean the IAC. Also do the TPS mod to ensure the 0.7 volts of readiness.

Leave the exhaust manifold alone. Also, a bigger single exhaust pipe works better for the Magnum engines rather than dual pipes.

Get the Goodyear Gatorback belt for the engine. It reduces the drag on the engine that other belts tend to due.

As for the fuel injectors, try the B-12 Chemtool cleaner for at least four tank fillups. this past holiday, I drove 1500 miles round trip. Used four bottles of the stuff one way. Going home was pure joy when the injectors flowed sooooo smoothly. Sure, going up the B12 seemed like the engine was sputtering, BUT that is how it was cleaning them. Prior the engine was mainly hesitating often.

You can also do the IAT mod, but I would do the dual selective mod of being able to switch between two IATs. One in the intake manifold and the other in the air-snorkle intake.
