VF48, catless DP and boost creep?

1day · 05-11-2008, 09:17 AM

Has anyone experienced boost creep yet with a catless DP? Just wondering if porting the wastegate is going to be necessary on the new VF48 in order to run catless.

Do you have a protune or cobbs ots map?

Don't even have the DP yet. Just doing some research and weighing my options.

I have a catless DP with the stage 2 OTS map and I overboost. I kind of figured it would but I've been lazy on getting my car protuned.

I have a catless DP and tune and have no problems running 18.5psi. It's all in the tune.

The 2008 Sti is very sensitive to back pressure. To run a OTS map, with a catless Down Pipe you will need to A) get a pro tune or B) change the restrictor pill.
