stand alone or piggy back??
im searching the forums as we speak for an answer to this question.
Im planning to go FI next year but as of now i plan to stay NA with full bolt ons.
Should i piggy back or get a standalone ecu?
which would benefit most on NA for now

Although i would agree that Osiris is probably a good choice for basic N/A mods and low boost application's, if you are going to run a built engine with serious boost, i would go for a stand alone management, as the std knock control is not very good, and so as i have seen Osiris cannot re program knock control?
also i am reliably informed that it in fact doesn't listen after certain RPM in open loop, which would worry me should you encounter some bad fuel, most decent stand alone's have very comprehensive knock handling, and a lager map grid for all parameters.

For normal NA upgrades, uprev is the easiest solution / best fit. It can also be made to work with mild forced induction. The best solution for forced induction is most definitely a standalone due to more precise/reliable tuning and safety features (such as overboost protection on a turbo setup) that the stock computer is not capable of.

Ok Thx for all the help guys. Ya the plan is a mild boost from super charging. I would assume that the stand alone would be a lot easier. However if osirus gives the best results for the Mula I shall read on !!!! Need to find an uprev spot

Since you're plans are for SC which isn't prone to overboosting like turbos, the features of a full standalone are way overkill. Just get Uprev'd from an Uprev pro-tuner shop and call it a day.

not sure how long ago it was added, but you can log knock as well. To be honest anyone relying 100% on knock control is pushing the limits too much as it is. Even with (the old) 5k cutoff for knock control, a bad tank of gas or other mechanical issue will trigger the knock map far before 5k... the VQ knocks mostly in the 3-4k range. Not as much above 5k unless you've got a very serious issue.

I'd spend the time and energy researching who will tune it over what they are tuning it with
Either can be made to work very, very well...or can be an absolute nightmare. It's all the hands of the person punching the keys

Obviously nobody is recommending Osiris for big boost as it lacks more comprehensive F/I failsafes -- but still nothing that can't be added externally (J&S, ect). Anything over 500whp is standalone time in my opinion. There just isn't enough resolution in the boost areas.
