hey guys, i have recently made the following upgrades...
high flow turbo
fmic
cat, dump and front pipe
600cc injectors
ebc
pfc
fuel pump upgrade
z32 afm
problem is, boost only hold 13psi then at around 4000rpm drops off to about 9psi.
we have tested...
boost controler, actuator, bov, intercooler pipe leaks and all seem fine. my next step is to take the turbo back off and have it looked at (got it second hand of sau). does anyone have any idea what it might be if its not the turbo? also, what rwkws should this set up achieve? only getting 165rwkws which i know is WAY low. thanx guys.
