hey guys i've got a 96 Xplorer sport 2wd,4.0 ohv, 5speed manual, just wondering what mods you guys are doin to get the top performance and hp out of these engines, mine seems pretty weak, i'm running 33's with a 4.56 gearing and it still seems pretty powerless, i've eliminated the air box and opened up the exhaust, already, what else could i do to give it some moer ponies. also my truck runs fine but i haven't changed the spark plugs in about 30,000 miles would changing these help any with performance? can an exhuast leak also hinder performance? because i've got a lil one.
