Sounds to me like he was boosted.
Could've been using NOS as well.
As far as all the mods you have, a tune would by far
add more power than anything you've done yet.
All told, you're probably at the most, 6-8whp more than stock, with the Typhoon adding the most.
Plugs and ignition maybe added 1-2hp....tops.
Check in the SVT Performance Chat for the Tune Review "sticky", and any discussions you can find related to the Diablo Predator (1turbofocus-tune) or SCT XCal by Hypnotic Illusions (Wayne-tune).
