Went back to 12-17 maps and its all good...None of the DIC 1-21, 3-15, 3-29, 3-30 worked..

HMM, I have been having underboost issues with Jb4 above 15 psi. I have hunted for a leak for like 2 months but the car gains boost after every shift which leads me to beleive that its the wastegates, the solenoids, or a vacuum leak of some sort. I have changed and tested all the vac tubing and found one small hole in the tube at the rear wastegate. I thought for sure that this would cure my issue as boost increased on stock map but I still am under target when i shoot for 16 or better. I'd love to see 17.5 even though I am fbo now and should see 20psi if I felt like it. Was considering changing out my solenoids as they have 70K on them.

I have the same wastegate issue, keeps opening and closing. I think I may revert to the 12/17 maps as well and try it. Thanks for the input.
