homemade intake plenum
I know my sig is a 6.7 but I need to ask some 5.9er's about an afermarket plenum. I noticed that I gained 4psi of boost and my idle egt's are about 50° lower than stock. Also at 100mph with the edge turned up my temp was 1050°, so im happy there. But I noticed that the egt's fluctuate really fast and it climbed up to 1500° and just as soon as it does it drops once the truck catches up with the throttle. I will post some pics of it later but I know the truck pulls better especially on take off. My whole theory is that more air means more fuel has to be added so there will be a temporary gain until she levels out. Btw the intake is super smooth, i've just never experienced a new plenum, and advice will help and what alhave y'all heard or experienced
Thanks

I made my own stainless intake. It has a much smoother flow path and I also noticed a faster spool up and better performance on the take off. Here's a pic of mine.
