That's great, now I don't have to assume your following lol.

But yea. Now if the OP left just one cat on each side it would be an issue, plus it would save quite a bit of cash. It wouldn't absolutely NEED custom tuning...because the AF's would mix right. Since a PI head swap won't throw them off as much as it does going cat-less. Therefore he could take advantage of the compression via PI swap. Offing all 4 cats destroys that. The truck will be nothing more than an obnoxious slug because it can't mix correctly.

 

no custom tune, and ya its gutless haha. I am trying to put off doing that until i get all the mods done i want. i got good gas millage going from Montana to Oregon and back, above 18 average. but i couldn't beat an old van off the line hah. once i get the turbo setup, ill ditch the edge cs2 and do a custom tune with everything i have done and call it good. Which brings up another question. What is a good place and or company to get a custom tune wrote? and what can i expect from that?

 

I'm not sure, I haven't kept up with that. However, if you throw a couple cheap cats on there, the difference will be night and day. That swap doesn't require a tune to make it worth while.

 

i still have the upper two cats, or resonators, whatever they are. and the upper two o2 sensors have not been touched or modified in any way. it does throw a code on occasion that i clear but that seems to be the only difference other than sound. Anyway, i am not to worried about how it runs currently unless i am going to hurt something. I just want to know if there is a supercharger, of any kind that coms with an intercooler, that i can bolt on with pi heads and get a custom tune wrote for. also, what else will have to be done? injectors I'm sure of, fuel pump maybe? what about mass air flow sensor? is there anything else that needs to be done first?

 

white89gt, do they want me to do all the modifications on this list, or are there a certain few that are more important or what?

This is a great how to video as well....

 

Well yea, throwing the a couple cats back on is just an option. Running the way you are isn't good for it. I can't tell you to what extent, the plugs will take a hit for sure, economy...If you not getting lean codes, that's good. If you are running lean, there's a danger there.
