Default Street tuner and Utec or Hydra?

I currently have a street tuner which for tuning fuel and timing its great. With my application though launch control would help greatly. I would also like to add nitrous later which the street tuner also does not natively support. My idle also needs to be raised which I apparantly can't do with the street tuner. My question to you is do you think I should keep my street tuner and add a utec for more control or go straight for a hydra? Anyone having any major problems with the hydra?

you can adjust idle with ST.

they will have their pluses and minuses. does keeping OBDII compliant matter to you? If so stay with ST + UTEC. THe biggest draw back to that IMO is having to run two systems and switch between them. Obvisously having just one EMS system would be simplier in the long run.

I love the ST+Utec combo. What one can't do the other can.
I don't think you can adjust idle with ST but I think you can with PT.

There is definetly no Idle adjustment which has been a real annoyance since I have a dr725 and modded injectors. The car stalls when coming to a stop at least a few times a day. How much more did pro tuner cost? The only reason I am shying away from hydra is the intial set up seems pretty complicated.

i think protuner is like 1300-1500 iirc.

I would call cobb and ask them about that feature, WRX ST SW has it. . .

Hydra all the way.....initial setup is not that bad. Tell Phil what you have he gives it to you. Idle adjusment is kind of a PIA but with Phil its not that big of a deal just patients in getting it right.

I remember reading a thread on the Cobb forums, someone had problems with the idle adjustment on the ST. They worked around it for now by using ecuExplorer which did the trick.

If you cant adjust the idle with streetuner, make sure you are running the current version.

FYI, the current version is 1.5.0.3

Regardless of idle problems, if you really want to go big power I would suggest a Hydra.

Lot's of good choices out there just pick one that suits your current and future needs adequately.

Big Valley's been using Hydra from the EVO vs. Subaru Shootout on. I gave them a secret weapon for the weekend and I hope to see them run 9s

Thanks,
Phil
