mac79 Posted September 28, 2015 Share Posted September 28, 2015 I have an old greddy profec no display just dials. I have noticed high boost seems to be a bit lest responsive but on low it seems fine. I looked at the dials, low and high on in the same postion yet i get 1.0 bar on low and hit 1.2 bar on high. I would have thought that high would have to be turned up more to get 1.2 so that makes be think there is a problem with high boost channel. Any ideas before i look at buying a new controller?

johnny g Posted September 28, 2015 Share Posted September 28, 2015 Is it something to do with the Gain on the unit? I had an old school Profec on my first MR2 Turbo, in the end I binned it for an AVC-R, although there's better and easier to use boost controllers now.
