Well I have a 2000 TJ with the 4 banger. I grew up riding in jeeps and hunting out of them as a kid but I'm almost 20 now and decided to get my own. My last ride was an 05 power stroke on 10 inches and forties with a motor pushing around 600 horsepower. So the 6 inch skyjacker and 35 procomps feel a little strange but I like it a lot either way. Of course I'm used to something pretty fast so the jeep is going to feel slow, but is it normal for it to take awhile to get to speed and top out at only around 70-75? Bare with me, like I said I'm new to actually owning a jeep and driving somewhere besides a farm. Any advice or need to know things would be awesome. Thanks for reading guys!
