If you want to make NA horse power, you have to raise the rev limit so in my opinion a chip to raise the rev limiter is necessary to take advantage of cams, and your headwork all of which is going to peak at above 7K rpm.
The ZX1 does not care to live at 7K+ so ARP rod bolts are necessary to keep the rods together.
The focus guys are doing more because the ZX3 aftermarket for their version is hot with products.
Those of us with ZX1 have to import Mondeo pre '98 stuff from the UK which was very expensive even before the dollar died.
The ZX1 intake manifold is a killjoy for mods. Breathing enhancements are not going to work unless this pos is removed for a different version.

A chip is the final stage of modifying your car. Manual or Automatic, you never start with a chip as the first mod.

And I can't wait to see how my car reacts when I get mine tuned

With an automatic, if you're not doing a lotta mods and are getting an off the shelf chip, then it's the best first mod.

I thought one of the best first mods for a ATX was a Tranny Cooler?
I might get me one down the road.

That's the best first non-performance mod.

You don't need a Tranny Cooler unless you are racing it or running that car 24/7. Since I live in Florida I might as well get one of these just to drive around on a normal summer day. I'm sure most of you guys from Cali would agree on a Tranny Cooler is a good mod.

A tranny cooler is good for ANY atx. Heat is what kills our trannies early.
