1 - A Chip/module
2 - Throttle body spacer.
3 - Air Tube Intake Kit
4 - Exhaust system

Those, along with a nice clean and smooth running engine will give you some power.

I've looked around, its hard to find if one actually exists. I know they make one for 4.0 YJ's 2.5 and 4.0 TJ's but all of us 2.5 YJer's are screwed. But either-way before I sink $300 into it, I wanna know how much power I will really get?........ How much did Jet want for yours to be reprogrammed?

Chris, Don't know didn't ask. My biggest problem is my jeep hasn't sat still for over a day since I got it. Therefore, unless I go yard searching and find an extra chip-I cannot remove mine to send in. If anybody has a chip for a 1995 2.5L Wrangler,they were willin to part with I might be willing to be a test case if Jet wasn't to expensive.

I don't think you have to worry about the bumblebee sound, that is a function of an engine at high revs. I can't even rev mine much over 3000RPMs

If you are lucky enough not to have to deal with emissions testing, just take your catalytic converter off and make it hollow. It'll give you a bit more power and is free. You can also get an air intake system, there are some do it yourself tricks or you can buy a cold air intake...
