I was wondering how much of an egt drop you have seen after installing one on your truck. Any better spoolup? Any thing you noticed after install is what Im interested in hearing. I have seen the power difference it made on Wendy. Also how much of a PITA is it to install?
Thanks
Nate

Well the install isn't too bad besides modding the Trans dipstick tube. I really can't say what it did for egt's as I am always changing tuning...If I had to guess it may have helped 100* but it's a guess.

i cant speak for performance but i have installed one on a lly and the fit was great and install was easy . i could not tell an increase because i installed it at the same time as a cheahta turbo . probably money well spent .

If you look around, you should be able to find Pat's (McRat) write up of it. IIRC, he said that there isn't much benefit until you get over 3000 RPM.

From what I saw with my own, I saw a little quicker spool up and lower EGT's personally. I pulled a 20' enclosed car hauler type trailer on PPE lvl. 3 before the dp install and constantly bounced off 1350*. I pulled the same trailer more heavily loaded and saw continously 100* less across the board on the same tune. This is just my take on my truck. I have not been to the drag strip since this install so I have no other input.

I don't look at my gauges so I'm no help. I just know with the DP and Banks Ram Air, I got 2 mph and .2 in the 1/4 :driving:
