Just burning up what's left of the snow tires. Waiting for the thaw so we can put back on the coilovers and 18x9.5 rpf1s and smoke some real rubber and break some axles. We'll run this in SM auto-x at the very least this season. Got what I think may be a lousy tank of gas the last time (noticed it was going a bit slower). Took out 2 degrees of timing and it was all back to normal.

Nothing about your kit/numbers seems to be close to what my kit actually did.

Not sure what your tuners were doing. Not that they aren't qualified per se...but you really need to live with this kit for a long time to get a handle on how the twin screw reacts. Gotta keep in mind that boost is directly related to what kind of cam timing you run. With dual VVT this means we have a TON of flexibility considering there's about 50 degrees of sweep with both intake/exhaust. That means we can time things in such a way that the effective boost and combustion pressures are less for a given amount of air.
