cant remember which mustang magazine exactly but there was review on the 4.0 with basic mods that included the C&L, UDP, and MAC muffler. they said that for aftermarket exhaust, it was only good for sound no gain in performance. maybe this ties into the actual quality of the MAC? [>:]

You have to have a tuner for that intake. I am in the process now of saving money to buy a tuner. I have a post about that intake. Make sure you get a tuner or you will be running lean.

i wondered this also and looked into it. i think justin may need to make a larger side note on the products page to not confuse some customers. If you notice on the power package, shipping is free. on the tuner/cai alone and muff alone, shipping is NOT free. you may end up paying more out of your wallet on shipping costs if you purchase the items separately. that might also depend how how far away you live but then again, if you live close enough, you could probably just pick it up in person.

what would be a good choice of a tuner? and can you use the tuner over and over again as you get more upgrades? to tune the engine?

sct is the most popular and widely used in tune shops. diablo would be the next popular choice. Not as widely used (online anyways) as the sct but great overall because of its software upgrades via internet and its extremely user friendly interface. I own a diablo predator so i speak from my experience with it. others can chime in on the pros with the sct. you may come across other tuners out there from other manufacturers (SuperChips, etc.) but its to your benefit to get the tuner that suits your personal preferences and most of all, its compatibility with custom tune shops. "custom tunes" is where you'll get the most out of your car so the quality of the actual tune file is the real difference.

oh yeah, to answer the other question about using it over and over:YES. if you decide to change tunes or modify one yourself, you can do it as much as you please. Just be careful on what you change especially if you dont understand what each parameter does.

Amen to that. I'm pretty surethat is alot of people's problem, unless they take out a loan. But I try not to buy anything I can't afford.

I've got the BBK and it is a good looking intake. I personally didn't need a tune with mine but I ordered anxcal-2 from Steeda (bad move) and when I finallygot it to work it was aHUGE difference. Don't hesitate to get the tune as soon as you can afford it. You will really wake the car up.

Ok I dont mean to be post jackin here but, this is the way I see it because I was considering the same thing he is by just getting a CAI then a tune later. Ok so the intake will help some but they dont give you very much at all unless you get the tuner. So what you are saying is that 1. either that the tune makes it just that much better, because I have seen tuners that will give you 25+ horses with a intake or 2. The factory MAF and computer will not operate well with the aftermarket intake. The only reason why I ask this is money is tight.

you can buy it, but dont put it on. you can ruin your eingine/comp if you run too lean for too long.

I dont understand how that is supposed to make any difference, I understand the mechanics of engines and stuff like that but a CAI isnt that big of a increase in flow. I mean yea it does help. It helped my truck but I never burned a hole in the top of my pistons either from running to lean. I mean that is what your MAF sensor is there for. So atleast my thinking is that as long as your tube is the same or relatively the same as the MAF then it is detecting how much air is flowing into the engine when mean that they only thing that should effect the amount of fuel and air is the computer program itself
