Any idea why the 17 has nearly 3 times the HP and twice the TQ gains than a '16? Thought they were identical excpet the tranny.

Nope

'17+ is gen2 of the 3.5 ecoboost. basically a brand new motor, plus dual injection (port and direct injection).

I'm suspecting better overhead with the turbos, and the dual injection allows for much better fueling when modified without having to futz around with expensive direct injection parts.

Honestly after looking into it, it's the turbos and the exhaust manifolds. The exhaust manifolds are WAYYYYYY better.

So I'm thinking of getting either the Roush Pac level 1 (tune and CAI) or the Pac level 2 (tune, CAI, and cat back exhaust). I kinda like it quiet (I'm more of a V8 sound guy) but would consider the Roush exhaust if it wasn't too annoying/loud. I leave early in morning and my Raptor was loud as crap when I changed exhaust. Made it difficult to leave while barely feathering the gas pedal and cold tranny not shifting until higher RPM. I don't want that again.

Only reason I am even thinking of this one over a plain tuner is because this is my DD and I want to retain the warranty and not have to get a lawyer if I have an issue. I am willing to pay the dealer to put it in, and more cost up front if it can help save arguments later about what caused the issue. I wont be beating on it or racing or anything, i just would love to have more power and still have my warranty.

Any more info on these? I am not finding much info in any of my searches. The +111hp/+126tq seems crazy to me for only $1500 with exhaust and "possibly" still under warranty. I heard you can only get a 36k warranty with it and it may cost extra?? Will void ESP?? So if I ditch my 125k esp and get money back, it will make this an even cheaper upgrade granted I lose the extended part.

I am thinking it wouldn't really impact MPG, could be slightly higher or lower depending on how I drive. Of course if I get on it a bit I expect the MPG to go down but I'm thinking when just on my 80 mile daily commute doing 55 on hwy hopefully it wouldn't go way down just from this.

No need to get the exhaust unless you absolutely want to, and I'd only do it if it was for sure 3" from the y-pipe back without a reduction to 2.5" before going back to 3" again.

The power difference is with 93 octane, too.

dajohu

Wonder what the diff is with 91? That's what I get around here. Like a hit of 10-20hp/tq?

It does say on the page it's calibration optimized for 91. Also it can work on lower octanes which is nice that you don't HAVE to run high octane, especially since not everywhere has it.

chimmike

yep, sorry about that...if it's tuned for 91 that's even better. For me, I'd run 93 if available, but if it's tuned for 91, that tells me there's headroom and safety.

w00t692

Guarantee it'll run safely on either 91 or 93.

Looking forward to some more reports of installs.
