Hello All,

I've got a 95 XJ with the H.O. 4.0l. Can a person buy a 'chip' to enhance performance of this engine?

Look forward to any advice.

Dave.

Yeah....but why? It's much $$ for what it doesn't do.

Try Quadratec or anyone who sells Jet performance chips.

They're about $240 USD though...

i thought of chipping my 98 4.ol,
not all it's cracked up to be.
throttle body spacing is cheeper and
with almost same results.
(my 2 cents)

Thanksfor the replies guys. I'm curious about getting a little more pep from the XJ as we'll probably be towing a small utility trailer this year as we'll have tow kids. Any idea of how much HP gain is achieved with the throttle body spacer? Other cheap ideas?

THanks,

Dave.

Its worth it, if you have other engine mods as well. It won't do much unless you've got an aftermarket exhaust, conical/cylinder air filter, throttle body spacer, msd ignition or equivalent and possibly headers. Then the chip will help out, and it would be noticeable, but for it to actually do what it is intended to, you need to get some other mods for your engine.

Might as well swap a smallblock V8 for all the time and effort...

Seriously...go with a high flow exhaust and filter...get yourself some truck plugs and a nice cap and rotor.

It'll be fine...trust me.

If you want to no apenuts on the thing, get a different cam and put a nice header on it. Throttle spacers do very little as well as "performance" chips...

But hey, what am I saying? It's not MY money.
