Sorry I don't know where to put this thread... Because I can't tell if it is a Engine management question or a exhaust question. Well anyways my question is If I do a Catless up and downpipe including a tune, let say... Ecutek. So after I do all the mod and the time comes to smog the car. I swap back in my stock Up/dp for like one day just to pass smog... how Bad would i mess up my car? or would i do any harm at all? (due to the tune ecu running on stock parts for one day)

Sorry for the horrible sentence stucture...

 

I dont know anything about the Ecutek, but I know with the Cobb AP you can reflash the ECU to stock for getting smogged

 

you should go with a cobb. the uppipe you wont have to change back it will still pass without it. the dp and stock exhuast you should put back on. with the cobb you can change maps anytime from stock to custom

 

Oh sounds great, Thankz GuyS!

 

Go with the Cobb you will be very happy with it.

 

Only problem for me is going with the cobb it cost around 600 new and then i have to pay for the tuning part so i'll end up spending 1.2K or so right? so much MONEY XXX

 

Ed from EQTuning has a good package of the AP and an hour of tuning

 

Is he the one in davis?

 

yeah

 

Cool i'll take a look thankz guys

 

Cobb AP is around 550-650 depending on your car. The Protune is around 200 or so. The good thing about the Cobb is you can run stage 2 with the downpipe and then get the tune later. And if you need to go back to a stock downpipe, you can just relash the ECU to stock and once you pass, reflash it back.

 

Oh so i can Flash the ECU with the Cobb by myself and not going tho a pro tuner? hmm i didn't know that... Oh about the stage 2 you (06wrx4me) were talking about what kind of mods do i need to change in my car inorder for me to use Stage 2?

 

Another good bonus with the Cobb is that you can get a 100 Octane map in the future so that you can get extra horsepower at track days. putting in a tank of 100 octane and switching to a pro-tuned 100 octane map makes a big difference.
