OK, finally fitted the HKS EVC EZ, and for some reason the thing will spike sometimes causing the boost to go as high as 1.8 bar. Ouch, fuel cuts don't feel good.

OK, the thing works fine when I set it on third gear, then it keeps the boost at the level I regulate it to. But sometimes, when I'm just cruising on 5th gear, I decide to floor and the boost just spikes really high. Sometimes it happens on 4th gear as well. Nevertheless, if I take all gears fast, meaning over 5k rpms and shift, then the boost will be equalled thorughout all gears. Now, when I shift 1 through third moderately, then when I'm on the highway and I decide to punch it on 4th or fitfh, then it spikes.

Anyone with any insight on this matter?

regards,
LEE

I've had a similar problem. but I thought it was from my SSQ BOV when I installed it. I have an EVC too. maybe it came from that. or maybe evos don't like our weak gas

My brother has a brand new HKS evc and amp; it does that same thing, specialist tuner advised faulty unit.
Worth a try.
