You have any picks of what you used? Can you give a list of materials?

I am still going to do the leak down and see whats what...but i am leaning more and more toward trying a W2A intercooler and sticking my original radiator back in. I cant stand always worrying about the ECT's. I dont want to spend a bunch of money looking for a solution at this point. I think i might try and pick up a spearco A2W intercooler and try that route and see what happens. I dont mind really, i like working on my truck so i am not disapointed to much. I think there is a possability this may be to much intercooler, i really am glad i tried it, but it may be coming back off. Thats just my thoughts right now, they may change in the next 10 minutes...
. I really wish a could find a used whipple intercooler and give that a try to see what thats like. I can feel the fall weather getting here soon and im gettin antsy again....LOL. Unless i find some serious leaks this weekend, that my plan. I think...

Well, I noticed a little bit of lag (expected that), but no performance gain at all. I thought originaly that it may have felt a little better, but like i mentioned back then, it could have been just the fact that I had not driven the truck for over a month. Its really odd to me that i would have this result considering all the positives that surround having an intercooler. I really expected a lot more out of it. I will give it the leak down test this weekend and see what i got. I really hope to find a leak to be honest with you, at least that would explain it. The only other thing that comes to mind would be my tune. With that, i am at the mercy of my tuner right now because i have no way to tune myself yet. I will take it one step at a time. Its not my daily driver, so i have time to do some testing and try and figure it out. I just wish it wasnt coupled by the ECT issues. First things first though, if i can find my performance problem, i will be more inclined to fix the ECT issues. Otherwise..........??? Maybe if i dont find a leak in my plumbing i can find someone close who can help me with some logging and help me with my tune, i would go back to the tuner but at a few hundred dollars a pop, its getting a little pricey for me.

The tune makes a huge difference, just comparing where I was at when I first installed the intercooler to now is nite and day. And I am still very rich, so now that my wideband is on I can get that straightened out and gain some more. The biggest thing that I notice is how it keeps pulling so much harder in the upper RPM's where before due to the heat and timing being pulled it would start to fall off.

I hear ya brother, but here i am with my intercooler between my legs looking all sad and what not....
Thats where i was hoping for my gain as well, in the upper R's. I even lost about 9/100ths in my 60' times. I was running consistant 1.90's - 1.92's.....the other day the best i could do was a 1.99 - 2.03........
