chip or CAI for performance
 
i was wondering what would give best performance and fuel economy for a 4.7l wk, a performance chip(and by who?) or a cold air intake?where would my money be best spent. i have read that performance chips only work for a while on a wk computer because of its ability to learn. i read that superchip and jet chips have this same problem is that true?

Many people with the chips just disconnect there battery every few months so the computer doesnt recognize the chip. Hope that helps you decide!

had no idea it was that simple.so why do people that complain about jet and super chip and say that the wk computer re-learns on its own do that thier self. i would like to go with a chip if its worth it. but what about a CAI?

Superchips isn't a "chip", actually I don't know of many vehicles that you actually "chip" after the early 1990's. Everything is programmable these days.

Superchips is a programmer that copies the factory tune then overwrites it with a modified tune of your choice (it comes with 3).

It would be impossible for Superchips to suddenly disappear.

Go with Superchips... proven hundreds of times over and over again on the forums and probably thousands of times across the platforms they support.


Many reports have been that intakes only seem to provide minimal horsepower and increased throttle response. There is a gain, but if you don't pair that intake with some sort of exhaust, you won't notice much more than a new noise (which could make you think you are getting better performance). You most definitely will feel even less of a difference if you don't have some kind of tune.

how much of an improvement would i see from this programer over stock? i would really want is more acceleration from a stop than what i have now. ive read that to really see a differense in acceleration or power i would need a different cam. would my money be better spent going to a different cam or would the superchip programer do just about the same performance wise?

ive installed a k&n cold air intake 180 degree stat and a ported polished throttle body ive seen great improvement i just havent pulled the trigger on an exhaust and the superchips thinking about it tho!!!! you should deff consider how much you want to spend and how much performance you will get with the money you have

well i guess a performance chip or a cold air intake are about the same in cost.i have no idea how much a performance cam would run. i would consider all three if i knew for sure that it wouldnt be a waste. its just that from what i have read some of the performance upgrades like the performance chips are just hype.

IMO, HiddenTalent has a hiden talent. He is right on with everything. As your first venture into modding, the SC tuner is your "best bang for the buck", and would be a great first mod, especially if you get the added Advanced Transmission Tuning App. (ATT). This is especially true if you plan to do any off-roadiing. You may see as much as 10 hp. but, as others have said, if you want more gains, you'll have to throw a bunch more $$$ at it.

Your stock intake will be more than adequate, unless you plan to get into some very extensive internal engine mods. Just remove the lower drain cup in the airbox (if it's the same as the 5.7) and attach a 3 in. aluminum tube to it. Run it to a place behind the grill and be sure to punch a small drain hole at the lowest point in the tube so you'll still have the drainage capability. Then add a K and N or TrueFlow drop-in filter. Since an engine is just a big pump, only capable of processing a certain amount of air for a given displacement, the air processing capability of the stock intake system is more than adequate. Your goal is to make it as free flowing (low restriction) as possible, and still provide adequate filtration.

A good low restriction custom or aftermarket exhaust of the appropriate size is also a good investment, both for performance and economy. Don't know what the 4.7 guys are using, but the 5.7's work well with a complete 3 in. system. Just be careful not to go too big or you'll end up losing power. I am sure the 4.7 guys can chime in and tell you what works best on them.

A camshaft swap (I am doing it right now on my 5.7) IMO should only be done after the intake, exhaust and tuner have been done. Otherwise you're doing it backwards and won't realize the full potential of the cam. If and when you do the cam, make sure you research it well, and do the complete, recommended kit that goes with it. Again, you don't want to do it half way, if you're going to toss the $$$ at it. The cam and kit that I am installing has been dyno proven to bring ~50 hp and 35 ft. lb. of torque, but at a cost of ~$1000, and that's just for parts. If you want to know more about what all optional/should be changed, just ask. Again, research as much as possible, all the cam grinds, kits, accessories, to reach your desired goals.

I have an intake with no exhaust and notice little gain in power, however it does sound great... I plan on putting an upgraded muffler/exhaust in the near future so the two should compliment each other nicely. As for the SC tuner, i am interested in one of these as well, i've heard only good things about the superchip but i see more guys selling theirs than writing great reviews about it so it puts me in a predicament.

Also, highly recommended for improved throttle response is getting a ported throttle body... they go for right around 180 and are a great improvement to your 4.7's personality.

to answer your question though, i went first with an intake, i will be more happy with it once i get my exhaust put on and then i will look at getting either the SC or the PTB. So if you want to just get one thing for maximum performance i'd recommend the SC between the two.

ive heard the same stuff about superchip as well i have also heard that stage 2 jet chip was suppose to be pretty good,theres alot of different storys out there about chips good and bad. i was thinking about just saving my money and just go with a really good cam but if i was reading correctly you need to have a performance chip first for it to make a difference? the CAI and the exhaust sounds like a must do but after that i believe you would go with a performance chip

im not sure about the whole cam thing... i know that there are two CAI's for our Jeep, the AFE and K&N... most people like the K&N better because of where it hooks up on the motor but its quite a bit pricier... the AFE can be easily modified to fit just like the K&N... i did the AFE. Also, i'd stay away with Jet Chips... if you want to get a tuner stick with a programmer like the SC, there is a lot of support for that company on this forum and not a lot of good stuff about JET.
