Has anyone taken a die grinder and made the hole under the wastegate flap bigger ? Did it help and how much ? I know with stock turbo and gate I saw 38psi boosht and 96psi back pressure ( shoulda left my uppies leaking). Normally was 33-36psi boosht and 75 psi bp .
Now gonna be running a TN drop in, with a 1.0 turbine housing and my buddy is gonna try grinding out the whole a bit to see if it will help with back pressure.
Curious as to what it will do
