Nice work. Doesn't look much tighter than the 2V and about the same as I remember the Terminator 4V.

Getting those "trumpets" tuned in may be your least concern...have fun!trumpets'
"Don't forget to smile" was the most important thing!!!!!!!!!!!!!!!!!!
Exactly! If this is the tune exactly as it came from Ford Performance, then it's going to run chronically lean with that big tube on the intake. The engine will think there's less air going in than there actually is. It'll have other side-effects too because a lot of the engine functions like spark and cam timing also rely on accurate data from the mass air flow sensor. The good news is that it's a quick fix for someone with the technology to do it.What tune are you running on it right now? The stock Ford Performance tune is set up for the stock air box for the year of motor you have. (15-17 ?) Hopefully you have addressed that seeing you have the larger JLT on there. The larger diameter at the mass air flow sensor changes all those algorithms. Your damn near there. Great job! Cant wait to see what numbers you make!
I ran into the same issue as you with the exhaust. I did a 3 inch to 2.5 reducer as well and reused my 2.5 exhaust. Its costing me some hp and trq i'm sure. I'm looking to switch over to the 3 inch mid pipe and run dumps this summer.
Note to the OP - if you want to see how the engine really performs, install the inlet duct that came with the controls pack on the engine. Even if you don't drive it anywhere because there's no air filter, it might make the engine run better in your garage.
