Hi, have a new PFC tuned (by Ray) for intake, cb, and dp. I'd like to add a muffled midpipe from Ray but don't know how to make the proper changes in my Commander. Does anybody have any idea what I should do? Just call Ray?

 

Yea, I ordered my PFC from Ray and it was tuned by him for my listed mods. I have ordered other stuff from him before this. Later when I bought the the resonated MP from him, I asked him the same question: "How much more fuel should I add?". His response, "Add a little more in." ,such a great answer. So much for user support from him on the products he sales. That is why I did not send my injectors through him for enlargement.
I added 1% more fuel starting around 10PSI boost and up to 2% around 12PSI+. Another way is to look at a map set that has mods like yours.

Go ask Ray and see what he says to you. We all would like to know.

 

A little off topic but, I'm considering that midpipe as well and was wondering how "muffled" it is. I've heard the Pettit one which is indistinguishable from stock in my opinion. Is it a true muffler or just a little bubble (like the old cherry bomb mufflers) in the pipe?

Thanks,
Alan

 

It looks like the old Cherry Bomb but works vey well. With it, my non-seq turbos are only very slightly louder than with the cat. It is a necessity with a non-seq or single turbo car as far as I'm concernd.

 

Thanks guys. When it comes time to order that part I sure hope he offers me some more thorough advice than that!

Max Cooper is using that resonated midpipe and he dynoed 24 additional HP after putting it in. (I think it was Max, at least) 24 horsepower for $329 is a hell of a deal if you ask me.
