Yes, the MBC only adjusts boost, and the S-AFC would adjust your AFR's.. That covers the two major concerns you woulod have and their a great setup if your budget minded.

I think the Utec is easier to use once you can get used to their "text only" interface... honestly, their both easy to work on once your comfortable with their interfaces. Both can be used on any car regardless of modification level. The XEDE has several maps available, however I recommend some level of custom tuning regardless of either platform. The honest truth is no "downloaded map" will adequately address your specific car, anyone who tells you otherwise is not being entirely honest with you. However downloaded maps are always a good starting point. There aren't many for the UTEC offered by TurboXS, but there are about a dozen for the XEDE. There is one difference though, the UTEC has alot more user support and there are user maps and members who have alot of experience and can help you out. The XEDE doesn't seem to have that same level of contribution.

Neither the XEDE or the UTEC have AFR listed in their logs, the problem isn't that their not capable of it, but that our built-in O2 sensor isn't accurate enough to tune with. Thats just an unfortunate fact about any narrowband O2 sensor on most production vehicles. With that said, the TurboXS Tuner can be used in conjunction with the UTEC and you can log AFR data with your tuning logs. The UTEC also has an optional MAP sensor to show boost pressure in your logs. Additionally that Map sensor can be used for closed loop boost control giving you a very capable boost controller solution (both are capable of boost control, however closed loop boost control is a UTEC only feature and an MBC or EBC is not needed)

I cannot currently make any more comments on the XEDE because I don't own one to test out. The only thing I do know in addition to the features I've mentioned when comparing is the Utec has direct control over timing, the Xede uses offsets.. You will have to make your decision on what you think is better after you research the pros and cons of that. Currently fuel control on both function similarly (MAF offset) However in the next firmware release, the UTEC will directly control the fuel injectors (I have been testing it and it works great) therefore things such as injector scaling, ECU rev and speed limiters, Boost cut, and fuel cut are no longer an issue and will not require a reflash on the UTEC. The Xede will require some level of reflash for any of those changes.

In all, you will never make a mistake with either product, the UTEC is an easier install, and has boost reading in the logs, and also will append AFR's if you get the tuner, its also capable of several programmed maps (5).

the XEDE should have wideband input at some point in the future, its slightly more difficult to install. However that shouldn't sway your decision, its no more difficult than connecting an additional wire or two. Finally the XEDE is capable of two maps.

Your local tuner should be able to tune either of these without much difficulty. However you should contact someone locally to see what they used, since local support will be more important overall.
