Default Cobb Stage 2 plus stealthback

I am going to be running a Stromung 3" dp with divorced wastegate and a Stromung secondary pipe with a high flow cat. The rest of the exhaust will be stock.

Wil thisl be a good setup for a Cobb AP stage 2 map or is this not going to flow enough for what the map needs?

Also is this likely to experience boost creep? If anyone has a similar setup I would appreciate any insight you might have.

In any case I will post some results. I think this could be an excellent combination.

For best results, you need a full TBE. Will your engine explode and kill 87 people with some stock components on it? No. Will you see full boost or full Stage 2 results? Maybe, maybe not.

You may see boost creep, you may not. It depends on how your car reacts and that isn't something anyone can guess.

Thanks for the info, but I already knew that nobody can guess what will happen. I was hoping maybe somebody would already have this or a very similar setup. Maybe my hope was misplaced.

If only someone would do some real testing to find out how much of a restriction the sti axleback at your power level really is. I guess we can only dream.

I ran a stealthback with the Stage 2. stock axelback. My max boost, even with the HWG map was 16.5 psi. It would rarely go above that level. When I switched to a full TBE (HKS Hi-Power mated to XS Race-pipe/downpipe), max boost jumped to 19.8 psi. I had to switch to regular Stage 2 map.
