im running a good set of 5x16s, it gets a little warm driving around, but at wot it stays under 1400, and it lights around 1800 to 1900, go for 5x16 or 5x18,you can try a similar size 7 hole injector, i think they might be better for a street truck but i have never had a set, you can always cut your pump back a little bit if your over fueled, and your have room to grow
