you should probably be up a good 15ish whp... a custom tune would gain alot more and help all the components run alot smoother together.
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:Thanx yo. I am planning on getting a tune @ Massive Speed cruise in in June. That will give me nice gain? How about the coil pack, and t.b.?
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 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.
