My warranty is fully intact and still in Japan, just shame it couldnt be exported with the car LOL. Never needed to use it anway, did have an aftermarket one for free, but the mods took care of that one early on.
just get it booked you wont be waisting your money.

Mike, always impressed you take time to post on here from a Prodrive point of view, and im sure others appreciate an insight into the thought process you go through.
Mikey, I think if your car was standard and you then de-catted the whole thing rather than do it in stages, you would be more impressed. You are talking of going from 215 bhp to 250 ish which is a reasonable jump. If thats not impressed you maybe there's something not right with the car? I did it in stages on most of my scoobs and always been impressed with the addition of a downpipe, mid range and particulary the top end.
Im sure you will be happy with the TEK3 though - but if you want further power then your eally need to start thinking of an Sti or a move to EVO land where bolt on power is easier / cheaper... The TEK3 fattens everything up and takes further advantage at the higher end of the rev range. I can highly reccomend headers too

There will indeed be tolerance differences between cars, but the ECU is easily capable of coping with these differences and running each individual car at it's optimum.
In simple terms, the maps in the ECU are not fixed (like the fuelling would be with a carburettor, or the ignition with a distributor) they are adaptable to the ambient conditions the engine is working in based on a feedback loop. About the only thing that is less adaptable is the open loop fuelling as it's simply not possible to monitor accurately and reliably enough for a road engine to cope with safely. In any case, if the fuelling is close enough and is set slightly rich to be on the safe side, all that happens is that the ignition adapts to suit. In some cases it's possible to reduce the fuelling in order to increase power but there will be a point early on where the ignition gets retarded in response to det and the torque therefore stays the same.
Boost, ignition and cam timing controls systems have feedback loops that monitor what's happening and make sure the desired effect is being created at all times, hence they cope with the tolerances very easily if set up correctly. That's where the skill comes in.....
It's very easy for someone to increase the boost, sort out the fuelling so it's not over-rich, and give the ignition control system some work to do by letting it have a bit more advance if it wants it but that's only a tiny part of the story. Fortunately the current ECU is easily able to cope with this but it's still possible to get into trouble in some cases by not making sure that the various features in the ECU to cope with det still work as they should. There's no point turning up the boost and taking timing out of the low det map for instance, if you don't match that with changes in other areas to save the engine when it gets too hot and dets. Guess what happens when you do that........

MY03 WRX:- Standard; Fast, kick in back boost, but dies at high revs, and third gear is fukcing crap after 4500 rpm.
AFTER TEK3:- Bloody smooth boost, with no discernible kick in back, but when that boost is still there at top revs, especially in 3rd and 4th, you know the car is better, you feel the car is better, and fukc me, it is so smooth it is unreal.
Nuff said.!
Well worth every penny, and makes an awesome difference to a WRX.

So I went and had it done and you know what? It's goooooooooood
It makes the characteristics of the car different enough to make it feel lke money well spent. My expectations for the results were not that high to be fair and the gains were modest. I think if i was expecting to see 300 bhp and 299lbs then i would have deemed it a waste of money. However experience has taught me that there's more to scooby performance than just outright grunt, its how it delivers it's power.
In a nut shell, the car now delivers its power harder and for longer. It does this smoothly and this morning on my way to work I found i was arriving at favorite corners quicker than usual and exiting favorite roundabouts in 3rd instead of second, but still enjoying some slip
Would i recommend it? Yes but only to people who understand that this modification isn't just about power hikes. If the person wants to see 300 bhp out of their UK car with just a decat and Tek3 then i'd tell them not to bother
So there you have it
Oh the before and after figures
Before 231/224 (MY00 UK + Decat) After 253/268

Glad you are happy!! And you agree with my thoughts exactly I ended up having my springs done yesterday as i was finding myself ending up in corners a lot faster than before, and getting the extra power out of the bends was starting to show up some undwanted handling characteristics
ENJOY!

see if you notice a difference in the economy as well
