Hey ya'll Ijust boughta 99 Jeep Grand with the 4.7 V8 and I was looking for a couple more bolt-ons to boost my hp. I already have an intake and full exhaust(except headers) and I dyno'd 175hp and 235ft lbs 2 days ago. I'm looking for things like a Superchips Programer or a flashed PCM and a bigger throttle body, maybe an under drive pulley. Basically anything that I dont have to tear into the block to install. If any of ya'll have any parts like this or can suggest others plz let me know.
Thanks!
