Congratulations! I know how good you feel about your truck now, compared to pre-intercooler project days. I can't wait to see how mine runs when it's cooler out, I'm sure you feel the same. Your truck will probably adjust to the timing and get rid of the KR after a few drives. You probably could have gotten away with even more than 16 degrees. Good job!

well for a guy who is not really a hands on type of guy..LOL, i still think it actually cost me less. If i had to guess:
$215 for the I/C
$357 for the radiator
$26 for the rad hoses
$119 for the charged air pipe
$200 for the various clamps and silicone connectors
$78 for the oil cooler
$200 for misc parts (tees, oil cooler hose, bolts, aux battery tray and cables, fan shroud)
All brackets, and flanges were made by me with Aluminum from the shop.
I figure i have about $1200 invested in the whole project + my time. They wanted $1650 + shipping for the Whipple kit. I dont think i would have got near the efficiency out of the Whipple kit as i have with the Dmax I/C. It cost me more time obviously, but i think i am better off. The only very minor drawback to the project is the addition of the I/C and oil cooler into the core support stack. Now i have 5 items in the stack (oil cooler, trans cooler, A/C condensor, I/C, and radiator), instead of 3 (trans cooler, A/C condensor, radiator). This brought my ECT's up about 20*, but only when sitting still. If i am driving the ECT's are a consistant 180*, but if i sit for more than 10 minutes, they will creep up to about 195*-200* and sit there...they never go over 200* though, even with the A/C on and at idle for 15 minutes. Even if for some reason i want to go with the Whipple kit in the future (if i find a great deal on Ebay or something), i am not beyond being able just pull this stuff off and put the whipple kit on. The only thing i would need to buy would be the lower radiator hose. I think i made the right choice (or you guys pushed me in the right direction i should say), just cant wait till the temps come down a little into the 60's and 70's so i can really have some fun.

Glad you got it all buttoned up! Do you think electric fans would help keep the ECT down? The flexalite duramax fans look like a good setup and should be designed to pull enough air through all the items you have stacked in front of the radiator.

Excellent work! Hopefully this makes up for those frustrating days putting it together! Are high 12's in your radar?
