Wezz44,
What injector did you replace #1 with? A used one? Good luck with that... A new one?
If you installed a new injector and it's still reading way off, I am going to guess it wasn't the injector to begin with. We get positive reads like that when the cam is worn out.
What happens when a cam wears out, as the PD's are apt to do, is the valve lift shortens and sometimes, dramatically. If you lose .040-.060" in lift, you will begin to notice the loss of power and smoke. Your injector's limit to modify fueling is reached at +2.99. You are close to that number on cylinder 1. Above that 2.99 number, you get a injector misfire read.
Remove the valve cover and look at the cam. Move the cam so that the valve lobe closest to the timing belt is UP. If you find that the exhaust valve cam lobe is very sharp at the lobe's peak, you have a minimum of .015" wear. It's probably much worse, if I don't miss my guess. You may also notice that there is galling on the base circle of the cam. These wear marks are the dead giveaway you have a badly worn cam.
We are quite well known for the cam kit we have produced and it's long-term success. If you have any further questions what to look for, and repair options, feel free to call or email.
Hm... I noticed something else. I saw the first set of address 1 measurements showed the water temp at 39c and the last set were at around 57c. Is that as warm as it gets? Your engine should run at 90-95c. I also noticed that the injectors, cold, are much worse and improve as the engine warms. Fuel temps were also quite low and that will also affect injector performance.
I'd still inspect the cam. You might get a fully warmed up engine temp and fuel temp, as that does alter the advance timing of your injectors.
