boost controller question
is there any kind of boost controller that could limt boost in the mid range yet still maintain boost high up for an mfi equipped rst
my prob is that im peaking at 21psi in the mid range and it tails off to 16.3 at 6k rpm,ava reckon its my intercooler,if you turn the boost up to get 18-19psi at 6k then the mid range increases and its dettin,could a boost controller be fitted to get 18-19 psi at 6k rpm and not let the boost in the mid range go past 21psi
