I have an 07 XK. Has a CAI and a Hypertech Max Energy programmer. Getting ready to do exhaust and wondered if high flow cats are worth the hassle? I've heard that they may cause a CEL? Just curious so I can get it done while I'm in there.

Does anyone have experience with the 08 manifold on the wj 4.7? air ram claims 20 hp+
I want to do the fast man 72mm throttle body at the same time I do this. Is this going to make a noticeable difference? I am also having some trouble finding out how to get sct tuning done. With this manifold it is almost required.

Where do I get a programmer?

Who do I have do it? Are there people on here who can?

I'm sorry for all the questions but this seems to be the best place to ask them.

You probably need to get your tune re-done how far is it winding out? Like 5.5-6k? You might have too aggressive of a tune I am about to get a the vivid linq for my 4.7 you can set all your shift points and do all of the tuning yourself. I'll let you know how it goes I'm pretty excited

When was the last tune up? How many miles? If your cat is losing efficiency, new 02 sensors won't fix it but may improve fuel inefficiency which may look like it helped.

Running the superchips 91oct can tune.. Just frusterating, was running fine prior to tb install.. Lol before it would almost not gear up quick enough like stay in 2nd lil bit too long and now it doesn't stay long enough.. If I put to 87oct tune u think that would help? Thought 91 would be best
