~Final Build thread~
Only tune it yourself if you're truely interested in doing it...and definitely NOT for financial reasons. There are aspects of the UTEC that are not user friendly and are only possible to tune with experience -- temperature compensations, knock thresholds, open/closed loop transition delays, and a bunch of other things other than A/F trims that when tuned correctly makes UTEC more or less annoying to drive.
Either way, I'd ditch the UTEC and go with Osiris. UTEC's are jerky transitioning in/out of boost, have a relatively high failure rate, tentency to blow coil packs, limp startups, ghost CEL's, dead batteries...and that's just my experience. Being SC you don't need the overboost protection anyways.
Why splice into 150+ wires with an unsupported / end-of-life box that slowly introduces gremlins into your system when you can plug a cable into the ODB port and tune away on your stock ECU..

Running zero gauges is possible, but it's a risk/reward question that you have to be comfortable with. They aren't cheap, but they don't represent a massive percentage of the total bill, and they can provide you with information that could stop you from damaging your engine. (They only provide info, though... YOU have to act on it.)
I've never seen a gaugeless VQ F/I setup go well. I'm a bit worried about your project but good luck anyways

to the closest Uprev tuner..
don't get me wrong I AM getting gauges(these are not the expensive parts).. I just needed opinions on this
I must admit, I am new to the tuning world (this being my first project) and I did not know it was possible for any tuner to tune the Osiris Uprev.. this will make it so much easier for me
