I did the roush kit, cai, pulley, and tunes from them. They outsource the tunes to someone else. I had to call and email a few times to get the CAI to ship, that took like 3 weeks to get to me. I bought 2 tunes, 1 tow and 1 performance. They tunes were to have the rear o2's turned off, they never did. The truck went into limp mode over and over on the tunes and I think 3 or 4 revisions later, I just said **** it. The IMRC wasn't working. I did data logging. It went on about a month and I said **** it, called JDM and within days have a tune that just works, she rips, I am smiling.

Another thing, the pulley they sold me I was told it would work on the roush charger, which it would no(unless I sent the blower out) as my snout is not threaded. I had asked for a refund on the tunes and still have not gotten anything. Whatever.

I wish I would have called JDM sooner. Nick and Jim were very nice and returned my calls/emails promptly, answered my questions, and I felt very comfortable dealing with them.

 

sounds like alot of work to install, are they worth it? are shorty headers any easier?

 

They are a lot of work to install. Solid gains, more than you'll get off of a cai or tuner. I've seen some claim an up to 30whp increase with a troyer tune on na 5.4.

If you want to do shorties....you might as well keep your stockers on.

 

Interesting on the stage 3 stuff. And ya do long tubes or nothing. Just spend the extra and get the better power.

 

So who would i get to install them? I am guessing the cats would have to be removed todo long tubes

 

Yes, cats removed. A shop could do them for you. Unsure what the cost would be.

 

exhaust shop told me they would not do it because of removing cats

 

This is the kit I was considering: OBX long tubes w cats and Y pipe...

The deal is not bad.

 

Those are not cats...

"no catalytic converters are included but can be purchased separately"

 

One thing to think of. If you have to get an emissions done you will want to keep your cats. I'm not saying your truck won't pass without them but if someone catches you without cats it's a good size ticket if they choose to enforce it
