I was previously MHD Stage 1 with DCIs, VRSF CP, TiAL BOV, and all redone silicone vacuum lines and I was getting a constant headache with a boost leak. I was going to take it in to the dealership for a recall and decided to take MHD off just to be safe in case they mentioned anything about it. After flashing back to completely stock, not stage 0 on MHD but fully stock, the boost leak is now gone and I can fully push the car again. Any ideas on what happened? Should I stay stock and wait for my catless downpipes to come in and then go stage 2 or try stage 1 again first?

How do you know boost leak is gone?

When I was on Stage 1, I could push the car but as soon as I would go past 60ish mph and hit 4th gear, the limp mode light would come on and I would get a 30FF boost leak code. Now that Im stock again, I can push the car as hard as I want. I was going 120 on the highway, with my foot fully down and the limp mode light never showed.

That could be true, but what happens is the boost target for stg 1 is much more than stock. So the boost leak is still there but its able to meet lower stock targets, and no 30ff.

Yeah I just realized that. I e-mailed MHD and they said that it's most likely the boost solenoids and to change those before reflashing stage 1 or 2 as the boost target is a lot higher.
