Stock Turbo

[Phoenix7]

if you have stock fuel system then you're better off leaving it alone...

Now if you get a boost controller I would not go past 10 psi if you keep the stock injectors. You'll also need a fuel cut defender since the higher boost will cause the fuel to cut out...

Now a lot of 13BT guys, especially the S4 peeps, tend to have problems with boost spikes...the wastegate can't handle the increased flow and you can blow your motor by boosting so high without the fuel to back it up. To help with the flow, a lot of people port the wastegate and that helps with over-boosting...

How's your car running? how long have you had it? mods? Mileage?
