If you are worried I would say stock is safest route until you can get a definite answer. From my understanding DAM dropping is when you are really in danger but I am far from knowledgeable on the subject.
Thanks - I've seen those but won't really be satisfied with just assuming the tune is ok and safe. I'd rather get feedback (at the very least) and/or a fixed tune from the company that put it out instead. Hopefully we get that.

Again - it would have been, at the very least, nice if MAP told us, soon after we post these results, something along the lines of "oh, if you are seeing those numbers at all, we suggest you flash back to stock and wait for our feedback/a fix.", or the opposite, depending on what they truly think.

I mean for all we know, this type of thing could be harming the motor the longer you drive with it and they shouldn't want us to risk our engines.

Too much to ask??

Well I mean, there is this page from their website...

In regards to your knock readings:

Quote:
FBK (Feedback Knock)- This should always read 0.00 during wide open throttle pulls. Cobb states that it is normal on the FA20DIT engines to register -1.41 to -5.00 during part throttle, low RPM cruising.
FKL (Fine Knock Learn)- Same as above.
Of course a an e-tune or protune tailored to your specific car is always advised and will yield more power and added smoothness and safety over any OTS tune. That said, unless you are seeing large knock values at WOT, it shouldn't be a cause for concern. Cruise/part-throttle knock is pretty normal for these motors on an OTS tune.

A well reviewed tuner, in the Seattle area, told me that a pro tune was not needed for stage one. OTS tunes are good enough, if only going to stage one.

Not needed, but will always be safer, no matter what "stage" or power level you are at.

What your tuner meant was probably "a stage 1 protune isn't a huge power gain over a stage 1 OTS", which is probably true. The real power come when you add a jpipe and other mods, and at that point a protune is pretty much a requirement anyway. But as far as being "safe" goes, a protune will always be better than OTS simply due to the fact that every car is different and an OTS map isn't able to account for every single little difference from car to car, whereas a protune is specifically made for YOUR car and the way it runs. And not only mechanical differences, but also geography, elevation, climate, fuel quality (this is huge), many more factors that can affect how a car runs.

I did write "needed". He said not necessary.
Surely, since I called him, if he wanted to, he could have easily steered me to patronize his services.
