I can't seem to find any significant engine upgrades for a 4.2L. Hypertech offers a performance "chip" but not a power programmer. I have some things listed below. Any ideas?

They also have a supercharger that just came out. It's $3500 and gives more HP than a 4.6 Mustang V8! You can check it out at www.autoperformance.net

Also, just a quick ?. How much more harsh is your ride with the leveling kit? I want to level off mine, but I don't want to sacrifice ride quality!

In response to the question about leveling off your truck: When I was getting my truck lifted, I wanted Rancho RS9000's on all four corners. However, the Rancho's were not long enough for the front. The people said that the 4.2L isn't heavy enough to compress the coils the necessary amount.(for a while, the front was about 1" higher than the back but now is only half an inch - hardly noticable) I went with the Fabtech shocks in the front. As for ride, it's great! I like a soft ride and the combination of Fabtech shocks and coils and Rancho adjustable shocks is perfect! My truck has a bad boy stance now.
