With most tunes, your peak horsepower wont increase substantially, but midrange is improved immensely. Never had a before and after dyno but I had heard with Waynes tune there is approx 15-20hp increase in the low to mid range where a focus lacks the most power. Def a worth while mod especially since you have a decent amount of other mods. Oh and the coil pack most likely wont gain any hp but help your car run alot better and unless you are very heavily modded, a larger TB isnt going to net much gain either, has better response but i literally barely noticed a thing from stock to 65mm.Bizzy_13 said:

Yes, you will see probably 1-3 HP from a coil and a TB, the response will be better so it is an okay mod, but you will see much bigger gains from the cam and gears. Just try to get all your bolt-ons done BEFORE your tune, as all that stuff affects the tune.

i would say dont waste ur money on the coil/wires since ur not going to see any real gain...some ppl say it smoothed out the idle...but i couldnt feel anything...and the tb ur not going to see any hp/tq gains however u will notice a difference in throttle response since the fc tbs use a different linkage...its one of my favourite mods so far

Yeah, I hate the lag in throttle response on the Focus. It's about my only big complaint w/ the car. So maybe the t.b. would be good for me. And the tune is a definate. I don't think Im gonna mess w/ cams and gears and such. Prolly a lot of $, and seems like a lot of work.

cams and gears aren't too much of a hassle. the only thing you have to do before you actually put the cams in for good is to take the old ones out, put the new ones in and rotate until the heel is facing the valve and measure it to find out what size buckets you need to get to have the correct valve lash. then you have to order new buckets using the measurements you took. put the stock cams back in until you get the new buckets in and then swap the parts out when they come in. not too hard unless you don't know what you are doing

yeah me neither thats y i paid someone to install them...i also had udp's (water pump and crankshaft), and my drivebelt done at the same time...helps to cut down the cost
So you'd rather waste the money on stuff that really isn't going to do anything for you...? For the cost of a TB (~$250) and coil + wires (~$150), you could get a set of stage 1 cams (which is about as far as you should go on a stock head w/ATX) and adjustable gears, which will give you dyno-verifible power gains, unlike the TB and coil, which will just make the engine rev faster and give you marginally better gas mileage.
But to each his own...if you're hell-bent on getting the TB and coil, go for it, its not going to hurt anything.

if you plan on putting a cam in there just remember not to put too big of a cam in it. ask any old hot rod guy. the biggest mistake people make is too big of a carb. and too big of a cam. also. if you put a big cam in there you have to replace your springs and everything which will become a hassle for you or more money to spend to have it done in a shop. call whoever you are ordering cams from and ask them what they recommend for what you want. they will know more than just about anyone else. also, remember with a cam that you will lose more bottom end if you havnt already. you'll gain up top but you'll lose some on the bottom. after all the work just get it tuned to get everything you can out of it. these are my thoughts folks. not necessarily right but not necessarily wrong. and yes, i know the focus does not have a carb. also remember that if you put a coil pack on there you will ruin your spark plugs faster. and if your going to do the tb save up and get the heads redone. but then again you could get the cams at that point too. my advice. get the cams, gears, and get it tuned professionally. there's your bang for your buck.

i agree w skaaddict in that cams/gears are going to give better gains than tb and coil...first of all let me restate that IMO u should NOT waste money on the coil unless urs is already going...if u must do something just get the frpp wires, costs less than $35...and second im not saying that the tb is going to make ur car a rocket...again IMO it made a fun car that much more fun...im just saying that its a nice "introductory" mod...plus u can do it urself w handtools as opposed to cams/gears...which u may not feel comfortable doing...ultimately though it is up to u

I'm not "hll bent" on anything. I was just asking a question, if you reread my first post here. And basically why I said I wouldn't really go for the cams is it just seems to be a lot of hoopla to go through for Zetec performance, wich lets face it, it's never gonna be a rocket ride. lol. It's not a money issue more than a b.s. issue. Im not really tying to make a super fast race car, (if I were I wouldn't have bought a Focus) I'm just trying to give it a little more energy, and touchier throttle response to make it a little more fun to drive.SkaAddict said:
So thanks for all your comments, and suggestions, I appreciate them. And after reading them, and thinking bout it. I think I'm just gonna go with a throttle body for throttle response and call my performance mods DONE. And I really want a F.C. ram air hood, for the scoop positioning in accordance to my Volant, and because they look sweet.
Thanks agian,

as i understand it the main reason that theres better response is because of a reworked throttle linkage...not a larger inlet
