BMC CDA is considerably cheaper than the viper (160 quids) I had a viper on my old car (corsa SRI) and i wasnt impressed with it! stay away from the cheap chips as said before, I have a dastek (which may be for sale soon!) Pete
the down side is that it will suck all the hot air from your engine bay..... more than likely decrease performance! If you've got a spare 160 quid, get a BMC CDA from stealth....
tegs are fuckin slow! ive out done one before from a standin start, but we were neck and neck top end! that was before the schrick also! both our clocks reading 155! I ended up melting my zaust to my bumber during that run in!
