Hi, dunno about right off the turbo housing but when I upgraded to a big 16g on my VR4, I broke her in with just the 3" DP, boy was that a lot of fun. When she got on boost, car was starting to point to the stars, then fuel cut
. Hopefully someone would try to install a free flowin muffler on our turbo diesels and post here.
I need to accelerate the destruction of my tranny so I can get a rebuild and get to mess around with the Alda and boost pressure.
