Most Spoon stuff is overpriced and easily outperformed by more inexpensive offerings. $1200 for an LSD when a Kaaz can be had for $800? How bout $550 for a 70mm throttle when you can get one from Erick's Racing for $400? $1800 for a pair of freakin brake calipers?!

Aside from any value judgements on the overall brand, you've misread the product description in detemining that these cams make power up to 9000 RPM. To quote:

"Factory B16A/B18C1 valve springs cam handle up to 8,300rpm, while the use of aftermarket springs can handle revs in excess of 9,000rpm."

This does NOT mean that the power peak of a motor using these cams will be at 9000 RPM. It means that aftermarket valve springs are capable of being revved to 9000 with the amount of valve lift created by these cams.

Bottom line, put it on the dyno and figure out where the power peaks.

Oh, and about the original question of getting this chip...don't bother. Have something reprogrammed by Locash Racing where you know what exactly is being modified, instead of some eBay special that's probably some kinda pirated wannabe-Mugen program that disregards things like sensors and error codes.
