What is safe boost level I can use on my stock but streetported engine. I have heard that you shouldnt raise boost more than 12 psi? But what I hear you guys almost everybody talks 15-18 psi.? Please help!

 

Depends on what other fuel modifications you have. If you have no fuel mods then don't raise the boost at all.

 

I have Walbro fuel pump
4* 720cc injectors

 

do you have anyway of controllering the injectors?

stock turbo? stock IC? downpipe? intake? exhuast?

 

HKS F-con+GCC
to4b
2,5" exhaust
custom IC (Front)
Filter
etc.

Just need to know how high can I raise my boost safely of course.

 

for people help you with the psi number they MUST have all the info you can put on.

The number of psi you can push int the motor is very close of your mod..

is this a full to4b with manifold , exteral wastegate etc. or hybrid on the stock exhaust housing?

the only real way to know is to take it to a dyno. start at 8psi. and slowy turn up the boost untill you can no longer add fuel. that is the only way to know.

you will need to do this anyways because you have to tune it.
