Default Should I get the UTEC?

My friend is selling his UTEC. He's got an 02 and I got an 02. He offered me a good price on it but I'm a little apprehensive about it. I am completely stock besides a GFB 50/50 BOV. The UTEC has the stage 1 and 2 loaded from Turbo XS. What do you guys think? Should I do an up-pipe before the UTEC? Or should I install it and enjoy stage 1 for now. What about boost control. I thought the utec controls boost but he has a manual boost controler too. Did you guys get any CELs with the UTEC? Thanks for the feedback.

the MBC he refers to is probobly the ABC (auxillary boost controller), it works inline with the factory boost control system. I've tuned many a "stage 1" car, to wonderful results. I'll tell you this.. properly tuned your largest gains are going to come in the bottom and and midrange, with a modest gain on the top end (there's only so much you can do with the stock exhaust and that turbo).

Boost response, midrange response, and usable torque in the 3000-5000 area are extremely vivid. It's nice to just keep the car in one gear and produce power at will.

As for maps.... you can completely change the maps yourself. The only thing I'd find out is what revision of UTEC he has. It's listed on his PCB. If it's < rev. 5.0 I'd just spend the $$$ for a new one. Trust me... I can't tell you why... just trust me...

As for up-pipe... yeah, they work... WELL... but without a means of adjusting what's going on, you may get a token of the potential to the ground.

It's ALL in the tuning.... don't let anyone tell you otherwise.

No you can't. In TurboXS lingo, "version" refers to software, while "revision" refers to hardware. There is no revision-specific firmware, all UTECs regardless of revision are currently able to run the same software, v3.1 being the latest released version.

What RiftsWRX is saying probably means the following:

TurboXS has quietly added certain hardware capabilities to the latest UTEC revisions, and future firmware versions will support it. Apparently, some UTEC owners will benefit from it, while others (like myself) will be SOL.

I have had the UTEC with stage 1 maps + uppipe (which was installed before I got the UTEC) for a month now and am thrilled with it. Given your mods, the stage 1 map will be fine, although I would recommend you install a boost gauge if you don't already have one.

Given the improvements of the UTEC, I would certainly recommend getting one if you can afford it. It smooths out power delivery where stock used to have hesitation spots (my experience, your mileage may vary) and midrange torque is definately improved, as mentioned by others here. I find myself staying in 4th or 5th on highways where as I would have changed down to 3rd before.

im using a stage1 map which i modified a little bit on the boost
curves (open loop) but the power is amazying. i dont need
any more thrust for streeting around. im using a blitz NUR
catback and drop-in K&N only (silencer removed).

my wrx vs a stock wrx... very big difference in 2nd and 3rd
gear. i lost em by about 2.5-3 car lengths during a wot
expressway entrance. hehehehe.

i don't know about 0-60mph 4.7sec as estimated by
turboxs during the summer seasons, but it can consistently
do sub-6sec without dumping the clutch.

the best part is consistency. without the utec my wrx
felt so different day to day even when the temps
were the same. i was convincing ford explorers were
fast sometimes. none of that anymore.

btw, those old M3's in stock form dont mean anything
to me any more.

I'm running stage one with only light mods. (K&N drop in and Prodrive axle back). No silencer or up-pipe changes.

The car makes TORQUE. I've been pushing the advance around peak torque very gingerly but have made some real gains. Upper range advance is fun to play with as well. Data Log Lab agrees. I feel (and sound thanks to the prodrive) like I'm driving around in a V8 engine except below 3000 rpm. I'm mostly likely going with some up-pipe soon whether gutted, STi, or othewise. Maybe throw on some intercooler hoses and I think 285hp/tq at the crank is entirely possible.
