I have to disagree with Blown_xa about VVti. I got about 20 torque and 25 bhp till 5000rpm with as far as 30Degrees Advance till 5psi boost. VVTi was tuned within an hour so it was surely worth the time spent tuning !

The Haltech ecu can handle idle control (make it a point that not all standalone ecus handle it so check out the specs first). Attached is my idle control page on ecu.

The factory ecu still sees everything and controls the vvti actuator just like factory, this is because of the way mine is wired. The halted sprint 500 doesn't control vvti, so that is how it should be wired. However, with the sport 1000 in your case.... It is wired up and can control vvti. It is no surprise you got gains, but that is because you started at a static vvti state ( you started with zero advance).
