was it worth it... did you see a big differ
Yes its worth every bit. The only year its doesnt work on is the 08 yet but there working on it. Also if you purchase osiris on uprev.com it comes with cipher which is a disgnostic program and also you can do a few other things with it. Tell him your mods.They will tune it for your mods. Get new mods and tell them and they will send you another tune for it. Free of charge when you get new tunes and what not. It can do many more thing than that also.you can search around on some threads and find much more info on it. The difference from it is amazing!!

what does the 2 degree timing done for you
Some ppl get the 2* because it gives a few extra hp. Also i dont think they have been able to do that on an 08 or not but i could be wrong.

is there down time on your truck with the uprev... is it mail in?
Nope: ), They send you a cable and a cd that you install on your laptop and you upload which map you want into your ecu. It reflashes your ecu to the map you choose, You will need your ecu# or vin # to give him when you purchase it. Its a real great program. Ivee done tried doing some 0-60 logs with it but I cant launch right becasue I either spin till 40 or so from a stop or if I take off slow I cant get my right time. Im going to purchase trutrax soon so Ill have traction to be able to do some logs and email them to uprev and get a better tune it.

I have had the VK PRO, as you referred to as the Stillen piggyback unit, with somewhat noticeable improvements in performance for past several months. I expected a more improved acceleration feel, but it does feel much quicker. I have a B & B catback and Stillen Long Tube Headers that seemed almost too loud during acceleration at first. But now, the engine runs smoother with an exhaust note that sounds like the OEM exhaust at speed. As you should know, the VK-PRO requires 91 Octane. Since I was running 91 Octane anyway, I decided to go safe with VK-PRO's Plug and Play with no adjustability. A Nissan Master Technician that owns a 2004 Titan told me that running anything less than 91 Octane is asking for future troubles. I assume if one plays with the ECU programming too much, any mistake in that areas could cause problems that might be more expensive. I haven't had any trouble codes, but some other users have. If I understand the write-ups I've read correctly, any deviation from OEM specs for the ECU or the tire/wheel sizes have caused trouble codes that Stillen was able to correct after-the-fact.

Sorry for being wordy, but I hope that this helps.

I also have the Vk pro and have been impressed with it so far. It is not a night and day difference but it is very noticeable. That said the truck is running smoother than before, and I am pretty sure its not the new toy infatuation talking.
