the biggest hp mods my L98 had at the time it was dynoed was used leaky flowtech shorty headers (****) with a catted y-pipe (2" to 3"), maganflow 3" cat-back, MSD blaster coil, MSD wires, new factory heads, airfoil (probably not much hp gain) air pump delete and thats pretty much it. I made 210 hp,290 tq at the wheels and I later discovered this "spark enhancer" I had on there (got it fior free) was throwing spark out, so I'm sure that held me back some.
