thanks for the feedback fellas.
To be clear, every one of SHife's Concerns has been addressed in subsequent production versions. It's too bad he jumped ship so soon.
Just so we are clear on a few things. To put things in perspective, here's what I was sent in e-mail:

Those conditions (100% throttle at 95 mph in 5th gear) will definitely generate high EGT. That's what the egt limiter is for. (the diesel truck guys do understand this) It would be wrong to disable the factory safety features and turn off the codes. The car should be fun, yet tell you when to back off, and if you don't... it will do it for you. We prefer an abundance of caution and an occasional limiter making itself known, instead of covering it up by fooling the egt sensors (or switching them around) and turning off the associated DTC. For example one competitor offers "EGT delete" and switches the sensors physical locations to "fool" the sensor and still achieves smaller gains than the kerma "everythign stock" tune in the CJAA for example, and runs 32 psi to try and control EGT. (on an "upgrade" turbo the factory runs at 24 psi) We will not do that. In fact, the EGT limiter in this tune remains 100% stock to retain OEM levels of safety.
And, DId I mention... The current versions of the Stage 1 and stage 1+ tunes have absolutely ZERO EGT issues at all... and are much more powerful than before!
And yes, much to my regret, Shife did get some stuff before it's released to everyone else. One of my personal failings is I am a VERY poor judge of character. Our development car is a manual transmission so i figured it might be helpful to have one or two willing beta testers with a DSG model to back up what we find with the in-house car. He sent me that e-mail about the egt and the MPG display on the MFA. IMO the EGT in this case is under somewhat atypical conditions that most folks won't encounter too often. (Maybe 30+ hours on our dyno and the egt limiter does not kick in with he test car, even during regen.) Also IMO no one really believes the MFA in any case, everyone knows those things are never 100% correct anyway. (I actually think it's kind of funny) I kind of left it at that with the last e-mail, I should have probably followed up sooner.
But this MFA issue, too, has been addressed in the current production tunes.
The current offering is the result of many hours of development time that includes 8 months of personal seat time by me and many dyno sessions that add up to something like 35 hours strapped down. And it shows because our Mk7 tune shows roughly 2x the percentage gains that are published by our nearest competitor. It avoids the throttle tip-in delay that the factory (and other tunes) have and is generally much more responsive and fun to drive than anything else available.
The flip side is that there have been some complaints about the tune being TOO powerful. That is something that's been "put out there" by our competitors, who say something to the effect of "If it were possible to make that much power then we would be doing it too". So if course, there must be something "wrong" if kerma is getting 2x the gains of a fully deleted car- even when the kerma tuned car has stock exhaust and stock emissions. The fact of the matter is, it takes a lot more effort and sophisitcation to achieve the results we do.
thanks for your interest and keep the feedback coming! It has been overwhelmingly positive feedback but we do welcome suggestions on what you might like to see done differently.
