    Yeah its weird it does it from idle out of gear and in first and second gear but not in 3,4,5th gear. Vacuum is 20-22 at idle. I am looking for any solutions.

        Do a boost leak test, my friends s50 turbo did the same thing and it was just a boost leak

                Got the Issue sorted. Tune had a Two Step build into it.

                            So the waste gate can not keep up at this point in its current location. Next step is to vent the turbo hot side housing directly. Also need to grab a ZF320 trans as the Getrag 260 can not keep up above 8psi. Wish I had done the swap when I installed the turbo. Otherwise the tune is being refined and pulling into the clean 11.8-11.9 at 7k. It pulls like an absolute train even over boosting. I am getting some street outlaw style wheel spin at 100+mph when the surface has a dip. Its terrifying. I love it. When I can control the boost the car will be the fastest thing I have ever owned and will easily be capable of whatever I want to do with it.

                                    It feels like it picked up speed as a build. Now If I could just get it not to creep I might actually be able to drive it. Right now I am going to start working on making room for at least a 295 as the 255 is hopeless.

                                            I kinda got 275's to fit. I would have just had to pull a bit.

                                                            Oh yeah. Imagine how it's going to be on my 215's[emoji23][emoji23] in serious need of more tire. When I had my supercharger traction was a complete joke.
