Default utec stage 2 base map vs tune

ive got a tbe exhaust, and am about to get a utec. since my mods arent very extensive, would getting the car tuned be worth it? i know the utec stage 2 base map runs rich and conservative, and obviously sacrifices some power because of it. how much power are we talking here? just trying to figure out whether or not its worth the trip to TXS to get it tuned.

I say its not worth it. I think you ought to wait until your mods become more extensive. No need to drop anywhere from 150 to 400 bucks on a tune and MAYBE pick up 10 or so horsepower.

Either pay someone to tune it, or get your own wideband O2 meter and tune it yourself.

Get it tuned. Not only are you giving up power, but your car is running so rich that you are blowing needless amounts of money on gas. Before I was tuned, I would only get about 220 miles to a tank; now I get closer to 300 miles.

300-220 = 80 miles
80 miles * 4 weeks = 320 miles.

See, it's like getting a free tank of gas every month.

1 tank of gas = $30

$30 * 12 months = $360

Tuning = $150 or so (less if you live by RiftsWRX)

$360 > $150

So the moral of the story is that if you spend the money to get tuned, you will SAVE money in the long run.

Ed...we'll try our hand at it (lol) then go to TXS if we figure out we suck. Don't go to turbotrix. It's not worth the shorter trip and saved money. Oh, your getting a utec, hmm, that's news to me

i just got mine tuned yesterday at turbotrix. i am at 297 whp and 337 ft/lbs torque after the stage 2 tune. i can feel a world of difference and it feels awesome to know that all i have is a turbo-back and intake...now i can't wait to do the other sick upgrades.
call turbotrix and talk to junior...that kid knows his s***.

ahh, guess i should read the fine print...sorry.
anyway, it took him about an hour and a half to install the UTEC and tune it. i had a greddy e-01 boost controller in it and he kept saying how much of a pain in the ass it was and how it wouldn't hold boost...so he threw a manual on it for $60 and got it to spike @ 19.5 and hold @ 17.5 for 290 whp and 322 ft/lbs torque. then he turned it up to 21 psi and got 297 whp and 337 ft/lbs torque. mind you all, i am only running a turbo-back and intake. he told me to get a front mount as soon as possible...which i will.
anyway, i have only noticed jerkiness in 6th gear when stepping on the gas, but junior said that it was normal for the sti with the UTEC. this is true, right???????????????

I say get it tuned.

i was just curious if i should port mine or not. Do you think running that much boost is safe? If you run that muich then you kind of tune around the boost creep i assume. Is your map going to run fine in all types of weather conditions (temperature mostly) or do u have to change it in winter and summer months? Thanks

well, like i said, i am getting an fp green turbo soon, so if the turbo goes, so be it. whether or not it is safe or not, i guess that remains to be seen.
i have noticed that there is a sputter at 3,000 rpm's at all gears, what gives? you think my tune would have taken care of that...i am going to call junior tomorrow and ask him about that. also, when i punch it in 6th, i see a spike up to 20-21 psi!!! what is that about?
