I was wondering how much would be safe boost for stock injectors and stock maf on my gt2871r .64 AR?

I have heard 11-12 would be safe with a GOOD TUNE (I will not raise boost unless I got it tuned, dont worry people ;))

I am planning on using an HKS ajustable wastegate

Please note that car is my DD during summer, so no need of running 18-20 psi on the turbo

I will be making sure of cleaning the injectors to make sure they flow OK before doing anything stupid

Also I got a Walbro 255 lph

P.S. I was planning on upgrading both injectors and maf but suspension started leaking... so I ordered a new one and was left with no budge for the motor lol. I now have to to work with what I already have so..

What do you guys think??

Thanks!

I would probably leave it at 8lbs of boost until you can get it properly tuned.

I would say stock boost , 7 psi is ok, but no more than that.

I woudl also suggest running elevated fuel pressure with this setup, I would run a 48-50 PSI base fp with the vacuum connnected
