Camaro Performance Chip

Has anyone used the velocity performance modules? My buddy got one for his 6 cyl and is happy with it but I was curious if anyond had tried the 4 cyl chip?? It is the cheapest chip I have been able to locate anywhere. I know they sell them on www.20horsepower.com but was wondering if you could get them cheaper anywhere else as well.

garbage!!! don't bother.... there are way better ways to spend your money!!

if you really want a module i would suggest the jet performance module. for the v-6 cars there arent many performance options so they can be a good investment. also, a four cylinder chip wont work for and engine other than a four cylinder...
