In general, if boost control becomes an issue based on wastegate capabilities you would need to seek out an alternate style wastegate solution external, for example.

Q What is the overboost CEL? A P - Boost Limit Exceeded. Q Is there anything else I can do besides porting the wastegate to prevent the creeping A Yes, get an external wastegate.
If you think of it as a hierarchy, then it should make sense. Using this logic, if the problem resides on the 1st level, no matter what you do on top of it, you will still have the problem.
A fuel cut defender will not eliminate the boost creep problem, but it will stop the fuel cut. Q My car seems to boost creep when it is cold out. Why is that? A Ambient temperature plays a huge role in how well your engine runs. In general, the cooler ambient temperature, the better your engine runs due to the laws of thermodynamics. The colder air causes your engine to make more HP more work under the curve with lower temps , therefore more dense exhaust gasses; therefore your car is more prone to boost creep when it is cold out.
If you live in an area that does not see colder temperatures AZ for example too often, then boost creep may never become a problem. Q I want to port my wastegate. What do I do? A Can you remove and install a turbo?
If yes, there are a couple of options. You can send it to a local machine shop port it, or do it yourself with a "Dremmel like" tool. Jun 26, By Lance Lucas A definition of Boost Creep, as provided by Garrett: "Boost creep is a condition of rising boost levels past what the predetermined level has been set at.
Boost creep is caused by a fully opened Wastegate s not being able to flow enough exhaust to bypass the housing via the Wastegate s itself. For example, if your boost is set to 12psi, and you go into full boost, you will see a quick rise to 12 or 13psi, but as the rpm's increase, the boost levels also increase beyond what the boost controller or stock settings were.
Boost creep is typically more pronounced at higher rpm's since there is more exhaust flow present for the Wastegate s to bypass.
Thanks for the answers, as always I'm learning a lot from you guys. And you thought boost creep was where someone came up to you and said they "really like your turbo car and it's one of the best forced induction cars on the road and looks stunning! Post reply.
