I don't think those are reasonable comments Armando - first off, the picture you attached is obviously of a very old system probably a prototype (yes, I know it came from Cartech's web-site ....); the picture of the system on the Turbo-kits website shows a vey different fabricated exhaust & manifold system for starters.
As to dual Wide-band requirement - yes, this is a nice feature for insurance, but by no means a necessity to any FI system, that has been tuned & mapped properly. Dual Wide Band is not going to be a closed loop control on any unit, merely a warning indicator that someting has gone wrong, or wasn't tuned correctly to begin with. I know the Johnson systems for example don't have that feature (at least yet to my knowledge) & he has had no failures that I know of. If a user wants to add it to this system, then it is a common charge that would be similarly added to any other system out there.
So you are saying there is another $2500 required for tuning? (Cost of AEM is immaterial since it's already included in the package) Think you need to shop around a little! Regardless of what anyone pays for their tuning of whatever system they buy, it's going to be the same for pretty much any system - maybe with the exception of CTSC which has no ECM.
I have no bias one way or the other on this system - however it seems like a good value at $7500 relative to other FI systems currently available.
Maybe your overall message is that $7500 is not the final total that one can expect to pay - hopefully no-one is naive enough not to realize there are other costs involved (installation, tuning, braking upgrades etc), but again, these apply to any of the systems out there.
