RB Rev TII Exhaust is in my Future, How Should I Prepare?
I have an S4 TII with a mild streetport (Pineapple template) and a custom intake. The wastegate is ported just below the diameter of the stock flapper door.
Question 1: I'm assuming that I can still expect some boost creep since I didn't weld a larger flapper on the wastegate arm and port the hole larger, but approximately how much creep can I expect?
Question 2: If I were to port the wastegate larger with a larger flapper door, is it possible to achieve stock or near-stock boost levels with the RB exhaust?
Thanks.

Yeah, you will likely get unsafe boost levels with the RB exhaust and a better intake. Port the wastegate, but be careful what metal you use for enlarging the flapper. There are posts on this forum showing erosion of the enlarged flappers over time according to what metal was used. Try a search to see what I mean. You might be better off to pick up an S5 turbocharger, port that and you should be OK. You would not need to enlarge the flapper on an S5.
Don't forget to add a fuel cut defencer no matter what you do with the turbocharger or the wastegate.

I've got the same exhaust as well as a custom TID. I upgraded my fuel pump and secondaries but hadn't gotten to adding any kind of boost or fuel control. I have a bad front rotor that is possibly from detonation. I'll know more when I start my rebuild.
