Cobb is ok, but their maps are way too conservative. You will end up spending $150-300 for a Protune or PDX map.

Utec, Unichip, Ecutek then HYDRA in this order

They were all ok but all had there problems. Hydra has auto tune capabilities, wide band and MAF sensor delete as an option. MAP based tune not MAF like the rest. The Hydra is the smoothest of them all IMO. I think that Ecutek is fine for 90% of the people out there and I liked it but if you change your mods frequently it can get expensive due to retunes. The Unichip was good as well just not as smooth as I wanted it, none of them drove like it was the stock ECU smooth transitions etc. The Hydra drives just like stock and is very smooth and powerful in what it does. It will grow with you in your mod path. If you want complete control the Hydra is the win. If you are going to due limited mods and nothing to crazy Ecutek is also a fine product.

utec with openecu "free" reflashing underneath.

i haven't delved into the reflashing completely yet, but there is no reason why i will ever need something "more" than this. the utec is there to give map switching and i trust its knock detection/correction more than the oem ecus. you get lc/ffs, mappable spare solenoid, shift lights, etc.

best thing that hydra can't give:
obd2 compliance.

Did you have it? I link my utec directly to the cause of my 2.0 failure. You have your opinion I have mine. As well reread my post I didnt say I liked it over the UTEC.

Id take a Unichip over UTEC any day of the week. Many tuners as well like it for its tuning ability maybe they will chime in. Many cars are still using it with great results. All EM units have faults UTEC, Unichip, AEM, AP, Hydra are no different.

yep. still do.

to the extent of my knowledge, the unichip has NO features over the UTEC. the thing with the UTEC is that YOU can tune it. to me, that is more valuable than an outdated EM that people dont support, nor can you fix it yourself.

i tuned my car from scratch when i swapped out injectors, turbo, etc...and my car is still running strong at 34k miles. the UTEC cannot be attributed to your engine failure, only the tune.

What are the advantages the AP has over the ecutek/utec combo? From what I know the AP can clear cells, have 10 maps, and has more options than that of the ecutek. Can anyone varify or add?

I would have to say its between the AEM and the Hydra. AEM is fine for a WRX but Hydra would be nice for an STI since it has AVCS Control.

I run AP under the UTEC and plan on adding the ST feature and still running it under the utec.

They both have points I like. The UTEC works well. Better and better as I learn actually. But there are just a few other things I'd like to have access to that the ST will allow and I don't think the UTEC will be capable of with it's current design. Rev limit for example (for the STi). Those CELs, AVCS access etc...

But the UTEC/Pro-Tuner combo won't be easilly replaced. So it'll stay.

this has been gone over 3 million times, but whatever:

1) 3 user defined RPM activated pull to ground drivers.
2) 1 3d mappable PWM spare solenoid pull to ground driver.
3) launch control / flat foot shifting.
