Hi there,
I actually just recently found that it was spiking to 12 but holding 10psi.
See the attached dyno sheet.
But it holds the 10psi flat.
I have the stock turbo, and stock IC on an rb25DET, with full 3" exhaust.
settings
hi = 48%
gain = 15%
set gain = 60 (I think I have these 2 around the right way... the 60 is the spool)
Does anyone know how to get rid of the spike??
wil..
