This has been used for less than a year. Only problem is that about 0.5% (or less) of the time, it cuts out (which causes the car to drive as if it were in limp mode) and then acts fine again if you wiggle the plug on the unit or just keep driving. Not acceptable to me. I replaced the harness at a cost of $75 two weeks ago and it still is doing it. Going back to HKS for warranty work is hopeless.

My loss is your gain. When it's working it's working. See power in my sig from 2 weeks ago. It also worked without a hiccup for the 400 mile trip out to Buschur and the 400 mile trip back. But since I track my car, it will drive me nuts worrying about the car missing a beat in the middle of a turn. Might be a simple fix. Might be on the verge of dying. I don't know.
