You have to trash the stock torque based logic to run aftermarket turbos that havent' been developed to work with the stock ecu. It makes the truck depend on the wastegate only for boost and power control. And the way the stock wastegate map is designed is really not for that and requires lots of iterations to make it work properly whereas other ecus just target a wg duty cycle on a known curve.
You basically have to trash most of the ecu and force it to operate like they did 20 years ago? That actually makes sense. When I saw in 2011 that they were calculating drive pressure using the compressor and turbine maps, then correcting the VE using drive pressure, I predicted it would take a multidiscipline team of engineers to ever get aftermarket turbos really working right. Resorting to older control strategies would do it too.
You had me till RX7 because you need to carry buckets of apex seals to run big numbers out of them, they do scream though.
You have to be kidding me? I am just getting into these trucks, but it is the most common turbocharged engine produced today isn't it? I know you cant just swap in some VF52's or Garret 60's because of the cooling (oil vs water) but it seems like someone would have jumped on this by now. I kind of wish ford had used oil cooling because I am fairly certain you could pull 700hp out of a pair of tuned VF52's on 93 and you could buy them with almost zero miles on them for like $100/per off of Subaru boards. lol
This community isn't full of people buying aftermarket welded tubular or log manifolds and bolting on random turbos. These guys spend coin, like on a Full Race upgrade kit (when it becomes available) kinda thing. I'm used to buying components separately and doing things like welded log manifolds with some sort of common flange turbo bolt-on, though I'm really keen on v-band now due to simplicity and sealing as well as lower likelihood of warping/leaking. There's no reason you couldn't have a shop fab up a pair of manifolds and just swap on a pair of water cooled garrets or something. Maybe a pair of GTXs.

Yes, without the known quadratic coefficients, and compressor mapping represented as the data you need you really can't control them like OEM.
After some of the ridiculous “gains” posted on the 5.0 with “just a tune” early last year, I take all threads from certain companies with a grain of salt. Nothing I read here a year ago lines up with the dyno info gathered since then.....just sayin.

Turbo swap is how it was done. I don't see why a turbo swap wouldn't pick up power on this engine easily, the stock 2.7 turbos are way too goddamn small to make power, they flatline at like 4800-5000 whereas the 3.5 turbos will keep making power all the way to 5800ish.
We finally ran it at track last night. our 2018 F150 2.7L Ecoboost ran 12.34 @ 113.44 mph in the 1/4 mile last night! We are very happy with that for the first time at the track with these mods on a 5000 lb truck. We have another session planned to see if there is 3 more tenths in it.
Mods List
CR Performance Stage 3 Turbos
SPD DP w/ Hi Flo Cats
SPD Mid Pipe with Res
Magnaflow 3 inch exhaust
Mishimoto Inter Cooler
S&B Intake
