VF39, VF43, VF48. Wanna know what the only difference in them is? The size of the wastegate.
The added backpressure from a catted pipe helps.
Or you can port the wastegate.
Or you can run EWG.
I am interested to see what Grimmspeed has to say. I am 99% I have seen many tuners say that the "creep" that some people see on a factory turbo can be tuned out as it is not real boost creep. I lurk more than post so maybe my memory is flawed.
