I disagree. HKS and Greddy are pretty even. Greddy only copies designs and proclaims that they're the greatest. Example: E-01, doesn't it seem that it copies the AVC-R and SAFC, while ripping of the Power FC all at the same time. HKS boost controllers and Ignition modules are very good. I don't see greddy making a DLI unit like HKS does to increase the power of distributorless ignitions. I also think Greddy needs to get fresh ideas to really excel, I mean who wants a Boost Controller the size of a DVD playback screen perched on their dash? IMHO Blitz and Apex'I have the nicest electronics money can buy right now.
