Sorry to rain on your parade, but the SpiralMax (along with many other "As Seen On TV" car products) is worthless. There's multiple articles found on the net, along with other automotive BBs that prove this. If it works for you, cool... just watch out if you have some people (especially those who have been working on cars for some time) jump down your thought. 
Just wanted to make you aware, that's all... nothing personal.
BTW, good call saving for the CAI... you'll be very VERY happy with the results.
