VVL switch points will have to be constantly changed until you find the sweet spot. The choice of turbo, manifold, and cams will all affect where the best point will be.

I found that the SR16 cams loved to kick exhaust first to aid with spool. The 20V cams like the intake first, and the exhaust cam about 800rpm later.

what kind of things should i be looking for? just seat of the pants feel? or maybe where i reach full boost the fastest? or just feel for the power to flatten out?

i will try to get it to the dyno as soon as possible but it may take a while.. im not lookin to go out an make crazy power on the street before tuning, but i do intend on having some fun

What base tune do you intend to run without dyno tuning? The most important part of a bolt on vvl turbo setup is the tune. I would get that thing on the dyno asap and make sure everything is spot on. Remember, you have less margin for error and there aren't many tunes that I know of running around that used a 2871r with an external gate with whatever injectors and maf you are running. I highly recommend you tune this setup as soon as possible and don't drive it much until it has been put on a dyno. I know it will be tempting but try to stay out of boost on the way to the dyno if you can.
