So Ryan and Dale,

Are we saying that it cannot be done on a SD vehicle with the Tweecer because of software limitations?

[93Cobra#2771]

Sounds more like an EEC limitation than a software limitation...

Remember...this truck is on a budget

I dont want to spend more on a cooler than I paid for the truck

7 psi pressure drop is what we found with my friends truck.

damn, was it clogged up? that's a big loss

Here is one guys findings:

Powerstroke Intercooler Info/limitations
I've been kind of wondering just how good this IC is over the past year or two. It works well , fits good and covers the grill nicely and is factory appearing, and does appear to cool the charge very well. As most of us know who run this IC, the core is very large both height and width. The tubes that carry the air charge are long for good heat transfer, but however because of their length, it has a considerable amount of restriction to flow.
Today, I placed a bung in the inlet side of the IC as well as the inlet manifold to try and ascertain the difference. With my 12 rib setup, I was making 19psi on the inlet of the IC core and just 14.5psi at the throttle body, meaning 4.5lbs of boost lost through the IC, piping and throttle body. I guess I should place a bung on the outlet side of the core to see the true drop in the IC.
Bottom line though, I think for the street the PSD IC is a good way to go say to 10-12psi, much past that you are loosing too much boost which equates to more heat generation by the blower.

Then he posted:

I went ahead and put a bung on the exit side of the IC. So I could get a true through the IC loss figure. It looks like 3psi through the PSD IC and 1.5 psi through the IC pipes and throttle body. I'm thinking The pipes are all 3" and mandrel bended so the 65mm throttle body is a reasonable restriction.

I will take 3psi drop for $167 Also I am running a 70mm TB


Someone must have stuck a Tater in your friends IC

Lee,

I beleive Richard is correct in saying that it is more of an EEC limitation than a TwEECer limitation. There maybe some tuning Gods out there that maybe able to get it to run correctly but so far the best way that I have seen is to just go to mass air to start with and save all the headaches..
People always seem to confuse the after market SD units with the Ford EEC SD units and they are not anything a like.....

You might send an email to Raymond Brantly at www.iwantperformance.net or drop him a line on the Yahoo EEC-Tuner site as he is the only Lightning guy that I know personally. He has tuned quite a few of these SD vehicles in the past and does a very good job from what I have seen first hand. He tuned a NA one when we were at Speedworks tuning Calib's car....
He may have a different opinion on the subject. It cannot hurt to ask him his his opinion as he has or had a Lightning if I remember correctly.

I will say IMHO it would be better to go to a MAF setup with the turbo. Note this is just MHO, YMMV....

I would use the $167 one myself as 3 psi on a street vehicle is not going to hurt you to much.
I had 2.5psi drop across an old one and it worked just fine.
The only time you really need the 1.5psi or less drop IMHO is when you are trying to make the max amount of HP that you can make...
Also you can always upgrade later on if you need to....or when funds are available.

Note this is just MHO.

Oh you can do it very easily, but it won't make you happy.

Basicly what all the SD folks do is tune everything over 2PSI as full boost / max load / WOT.
Which means, if the turbo makes 3PSI early in the RPM band.....
Anytime you add a little boost without going to WOT your tune will be FUBAR.

So, you can have a nice idle, good full throttle, and crapy inbetween.

Also what injector will you be using?
I don't see low slope / high slope scalars in the C3P* binarys.
So larger inejctors will not be easy to tune
