Chip my Jeep or spend the money on Potato Chips

So what is the word about performance chips. I hear lots of mixed feelings concerning their actually efficiency. I drive a 2004 Jeep Wrangler X and am currently going to school so if they work, it sounds like a good investment but if they don't I am not going to waste my beer money. Do any of you have your Jeeps Chipped and if so what improvements to fuel economy, horsepower, etc do you see? Just curious because my roommate at college thinks his chipped truck is the best thing around and I have no way to disprove him. Anyway, so if you can give me the low down on performance chips, what I should avoid or get I would appreciate it.

JEEP WRANGLER GF Peformance Chip

-OR

LAY'S Classic Potato Chips

thanks,
Micah

What kind of improvements are you seeing. If it only increases fuel by a mile per gallon it will take forever to pay off. Is there any other way to improve milage on the aerodynamic nightmares. (don't get me wrong I love it and if I really cared about the mpg I would ride a bike, but... If I can spend money now and save later, who wouldn't) I don't have a huge lift or outrageously oversized tires and my fuel economy now isn't bad, but there might still be a way to save a buck.

Lol, you don't buy performance parts expecting to get your money back. For that matter, you don't buy performance parts for a Jeep Wrangler expecting to get performance, unless its a bigger engine or stroker kit. 190 hp + 20 still equals slow. Heck 290 + 20 hp still equals slow nowadays. You gotta pay to play, and its going to be more than 700 bucks! Be happy with what you have and take him offroading. See who has the advantage then.

its alot more responsive,and feels like more power, it also sounds cool with the intake, its kinda got a whistle to it, as far as mpg goes i dont ever pay any attenion to that...IMO its woth the money....I also got a Borla header and full magnaflow exhaust, im sure that plays a role to

You need your butt dyno recalibrated.

To the OP:
Spend your money on mods that help. Gears, lockers,lift and tires.

Not worth the money dont waste it... I chipped, programmed recalibrated every vehicle Ive owned my Jeep was only one you couldnt tell any difference but what do you think you are gonna get outta a brick with wheels... I went with gears after I tried the chip, gears made a noticeable difference but still no hot rod. IMO spend your 4 else where

By federal (EPA) law, chips cannot change or modify any engine parameter unless the throttle is wide-open and the rpms are at or very near redline. Not exactly how many of us driver our Jeeps. It will make a minor improvment at the dragstrip, it won't make any difference around town or on the trail. Save your $$$.

Past two days I have been having idling issues. Turn jeep over. Does fine... Won't start or it will and just sputters and dies. I would have to pump throttle a little thats the only way I kept it running. Pissin me off royally cause it did it once, then not again. Then again, then not when I had someone to watch and think with me. Just today I was like... HMMMM maybe... well, easy lets unplug and check. Unplugged and BANG! Fixed and drives mint no issue with that starting or idling.


Listen to all above as they told me.. buy something better. Mine is broken in a few places due to anger and in the garbage at my shop. BTW noticed nothing at all difference in drivin it or MPG. Had a Jet Performance Stage I.

Moroney, try cleaning the IAC and it's bore, plus the throttle body bore, most likely they are dirty.


LeterBuck, get the Lays. Those "performance" cold air systems, Chips, throttle body spacers, etc. are a waste of bucks on a Jeep.

If they did improve performance, then fuel economy would suffer. If they improved fuel economy, then performance would suffer. It's a Jeep, not a ricer. Like said gearing is a better option.

Chips for the 2.5 and 4.0 Jeeps are a waste of money (unless you think unlocking the revlimiter, speedo stop and fan controls are worth $300 plus). The best you can get out of any brand chip is a slightly better throttle response (and that will disappear quickly). Chips for GM & Ford V8s and all the truck diesels make a real measureable difference - with the truck diesels having the largest gains. I preferr having the source codes and reprograming the ecu perameters myself on a laptop. You can add headers, CAI, catbacks, port and polishing, up the fuel and change the cam but if the ecu isn't changed for those items, all you can get is a partial experiance.

Thanks for the info everyone I appreciate it. Hope everyone else got their answers too. Looks like the consensus is to buy some potato chips! Mmm mmm not a bad option at all. Even with a big diesel you would have to wonder why dealerships dont have chips standard as an add on if it's worth it. Either way couldn't be more content with my jeep! Time to get some fog lights to install.

most diesels are tuned to the max from the factory, but some do get chipped....bigger heavy duty passenger/limo van chassis for example. but they usually get upgrades elsewhere as well....some manufacturers add in the margin of safety so the next model year they only need to change the tune and they gain power....like the new Ford Scorpion - the 2011 model can gain 10hp and 65ft/lb of torque from a computer reflash free of charge from the dealership.

with diesel chips you can add too much fuel and raising the EGT's too high...on the dragstrip for one pass you're ok, but towing your trailer on the highway you can melt expensive stuff.

Potato chips and beer is almost always the better investment

Most 'performance' mods for wranglers are a joke anyway. For MPGs skinny-pedal control is the best solution.

Aftermarket chips, custom tunes and programmers all have a place in certain car scenes. I run a custom dyno tune on my '03 Mach 1 mustang. Due to fuel injection adding things such as different exhaust, intakes, cams, etc. really confuse a computer and cause it to run differently. A chip and tune will cure most of these issues and increase power. There are a lot of fast cars running around with a bunch of money spent on it that is causing harm to the engine and they aren't getting all they could out of it because it isn't tuned right. The ever rising diesel craze has a lot of people hearing about chips/tunes. Just my opinion but the right and only way to tune a mustang with aftermarket parts is a custom dyno tune. Chips run around $300 plus another $300 to $500 in dyno time. It is expensive but I look at it like this. You don't buy new tires and not get them balanced. Same goes for aftermarket goodies.

Now I figure a jeep might pick up 20-25 hp with a tune (tops). Most people cant really feel that in the seat. I'd assume your jeep is stock and if it was me I'd spend the same money on a aussie front locker.

I can't mention names but even the best module gains about 5 hp and a little better for torque - speaking only about the 4.0 2000 to 06. Tuning with a laptop and program while sitting on a chassie dyno is much better for reaping the most for intake, exhaust, timing and fuel trim changes. I have a box load of these I tested and will be selling them at Jeff Danniels this weekend (they do have some use if you fooled with settings).

Only the Banks diesel progams (except the big Hoss) are safe parameters and don't jepardize any systems. The others are considered "for off road use" and dealers are prohibited from installing such parts.

I agree 100%. I keep forgetting its a 4.0. My cj has a v8 and I wish you all had one with me. Speaking from my other love, mustangs, I am amazed at the # of guys who put a e-cam and a cold air in a fox mustang and think they got a rocket. The thing sounds "good" well until it dies after idling too long.

IF YOU PICKED UP 20-25 RWHP IN A JEEP YOU CERTAINLY WOULD BE ABLE TO TELL THE DIFFERENCE. oops sorry for caps.
i have had several high hp cars
ranging from mustangs (had a single turbo 03 cobra making just over 1000rwhp,LS1 corvette (heads/cam/nitrous making 440rwhp on motor and 620rwhp on spray) now in a car like this chances are you wont feel an additional 20rwhp but in a vehicle that is only making ~200 at the crank 20-25rwhp is a drastic improvement. you will not see this from a chip on a 4.0!

Well sounds like everyone knows more than me. I think his question is answered but if he has any more I will let you take care of it.

That is only if the part was manufacured to meet federal requirements. You can manufacture a part to do anything and most are labeled "off road use" because they do not meet regulations.

accept your jeep-it is what it is. jump in it and take a ride to the store and get some lays--little french onion dip would go nice with them.
want performance, get a vette-want a decient DD, that's good in the snow and will take you just about anywhere you want to go, keep your jeep.
