alright i got my intercooler today looks like a nice unit polished down tubes and all. boots look ok but not as good as my mr bobs. i am on the road as usual and will be having a cummings shop do the install. my gears were just updated to 4. 10 from 3. 54 and what a difference that made. my towing over a 500 mile trip was much more pleasen't. i had a good reduction of egt temps due to higher rpm and was even able to use 5th up light hills now. so my thought now is to see really how well this intercooler does. i will install tomarrow and try to tow over weekend. i want to post how well it works and if it was worth the big bucks or not. there has ben a lot of talk on here about a intercooler as a wast of money but i belive it will help at least 100 degrees lower going up hills. right now i can maintain 1200 or less but at full power it will hit 1400 to 1450 so lets see if i can use full power and what the temp will be. i will keep you guys informend and let you know as soon as i can tow. by the way carl at all about diesel gave me a deal on it and i got it in about 3 days.
