hey guys i just want to know what is the safe level of boost to run on my stock 850 turbo? i have a cat back and a filter, what can i run safely everyday? my car has 200 000 km on it.

 

I would say to stay around 10 or so PSI.

 

10-12 PSI is safe. Do it right with an ECU upgrade not a manual boost controller.

 

I agree no more than 10-12 unless you beef up the motor

 

I have seen a few people run 15 with a chip and some sort of controller.

But yeah, I would say stick in between 10-12.

Ten is plenty of upgrade power.

Get that, an intake, and an exhaust and you're already faster and more powerful than an R spec 850.
