Hey all, so I got 424 a couple weeks ago, it had a stock cai box, so me being me I had to get a CAI that had JCW on it. I bought the JCW intake CAI from Way Motor Works, and got it today. It came with a Tune unlock code and a certificate of authenticity for a JCW tune.


So here is my question, it's a JCW WC50, and I just base lined dyno'd it earlier today at 259hp/260tq, so I am guessing i DO NOT need to have this tune installed. Is this correct? I am assuming I already have a JCW tune since the car is a JCW and turning some crazy hp.

Here's 3rd pull:

 

82 views? And nobody knows?? Buehler??? Is my breath bad?? :-p

 

If you have a JCW like the WC50, it is already tuned. So you do not need to tune it again. I would of thought being a JCW already it would of had the JCW intake already.

 

Me as well, but it had the big one with the flat panel filter. Should i make the unlock code and certificate available to someone that needs it?

 

My factory built JCW has a flat panel filter. AFAIK all factory built JCW's (which includes the WC50) have a flat panel filter.

It is part 2 in the following diagram after the link
