Yes. TurboXS, Vishnu Tuning or COBB!

That's the answer.

I think as far as tuning goes they all know what they're doing. Performance numbers will probably end up being very similar between all three.

I think it really depends on what you want, what you have, and where you want to go.

If you are a casual driver with no mods, or standard mods, then I would highly suggest the Cobb reflash because the price is excellent.

If you have a ton of custom different parts, Vishnu or TurboXS might have more flexible maps that they offer to match what you have, but you'll be paying a lot more.

Personally, I have the Cobb Stage1 and I think it's the greatest thing for me, someone without any other mods.

I went with Vishnu and I am a very happy, but frustrated customer.
I'm happy because my car is so smooth and fast, frustrated because I want more power (TURBO,IC, injectors...)
Seriously, I think all of the above choices will make you happy, it's becoming a large market and those three tuners have a lot of experience.

I have both a Vishnu/ECUtek ECU (Stage I) and also a Cobb AccessECU (Stage II), and have run them both in my car.

They are both excellent, and very similar overall... way more similar than different at any rate. Both are very smooth and provide great power.

The differences I have observed are these:
1) There's more boost fluctuation with the Cobb unit than the Vishnu. Under WOT the Vishnu unit pegs 15.5 psi and stays right there, wheras the Cobb unit jumps to maybe 17 psi briefly before settling back down.
2) The Vishnu unit is less resistant to throwing P0420 CELs. I get them all the time, sometimes even away from the highway. The Cobb unit also throws the P0420, but less frequently and pretty much exclusively when I'm on the highway.
3) Price: $750 vs. $395 to get started; $175 vs. $20 for reflashes.

The real clincher for me is the way the two companies dealt with me in regards to #2 above. Vishnu offered to cure the problem with a $175 reflash... Cobb would do so for free.

Both are great products, and very similar in how they perform, but price and customer service put Cobb ahead in my book.

yeah, i was leaning more toward cobb. i think they have been around for a while.

the reflash would be a first mod. driving a stock wrx is just not exciting at low rpms and i figured this would be a cure for that.

I think you'll find that some exhaust mods will do more for low-end power than the reflash. I installed an STi uppipe and MRT turboback exhaust system, and ran it with the stock ECU for a few weeks before getting the Vishnu ECU... The change from stock => uppipe+turboback was dramatic, especially at low RPMs. It's really the restrictive stock exhaust that limits low-end power.

Yeah, it's more money for the exhaust gear. A good, quality turboback system will run you upwards of a grand new. Uppipes are $2-$300.

I got my stuff used, and paid ~$750 for the uppipe and turboback. Keep a close eye on the classifieds and you can sometimes do real well, especially with a recent wave of folks de-modding and trading their cars for STi's or EVOs (my MRT system came off a car that was being traded for an STi).

If you don't do the full turboback right off the bat, the TurboXS stealthback pipe is a nice starting point and is less $$$.

Vishnu charges $650 now, not $750.

I just couldn't send all that money across the USA and have them ship a ecu out to me. I am in Mi. and I waited for Payn technologies to get their mustang dyno and ECUtek software. I gave him some time to play with it on other cars that I witnessed and talked to the owners. They reflashed my ecu about 3 weeks ago on the dyno and so long unichip

So that is my point, try to get Your car tuned at your elevation on whatever gas you run(94here in Mi). It will just be more specific and I think you will be happy like me

Question Old School

Has anyone here had any of these reflashes on any older modeled scoobies? I doubt it but you never know. Can't hurt to ask.

Well we reflashed our 1997 OBS USDM WRX conversion, 1998 rs/wrx conversion, rs/jdm VII wrx conversion and about a dozen other conversions. Do those count?

TurboXS doesnt do reflashes.

Why does everyone always overlook these simple things?
