Hey guys need help.I have evo 8 stock turbo.I installed kinugawa wg actuator (25psi),grimmspeed 3 port.the car is tuned on E85.yesterday I did 3rd gear pull all the way to 7K.boost spikes at 30# and tappers to 21# and holds all the way to red line.is this ok?I mean since I have 25psi wg I thought my boost should drop to 25psi and hold that way to red line,no?I preloaded wg using fp website.thanks in advance.

 

That is completely normal. It's a "small" turbo.

 

Your lucky I had an issue with my car not doing over 10psi boost leak test later on leaky throttle body gasket.

 

master,thanks man

 

i feel you man,i did boost leak test before tuning.i was expecting tb seals to be leaky too,but i was wrong
