The question is, are those numbers to the wheels or flywheel? Almost every aftermarket upgrade is measured at the wheels because people aren't using an engine dyno. However, since this is Shelby, they could be talking flywheel numbers which as you said would be a bit underwhelming.

I was thinking about this on the way home today. I kinda feel like it could be either/or at this point unless Shelby or FRPP come out at say this is flywheel numbers or wheel numbers.

Yeah the more I think about it, it almost has to be flywheel numbers. I HIGHLY doubt they get those numbers assuming the car has stock plugs and intercooler.

I'd put my money on it being bhp.

those numbers are not bhp or rwhp if you look at their brochure at the very bottom in fine print it says power numbers are only an estimation

The Shelby GTE is using the Ford power pack for the 5.0, and so I would assume that the ecoboost also uses a Ford power pack. Shelby quotes 340hp and 390 ft lbs.

And those are prob crank numbers, I'm sure rwhp is more like 300

When has anyone seen any factory based anything even from a Performance division use RWHP numbers? They are always crank estimates and can be under or over by a huge margin.

No one, I guess my point was, it's pretty unimpressive

Thankfully, the two or three days last year in which I actually considered waiting for this tune are now but a distant memory.

lol although an estimate, they have to be an estimate of one or the other and my be is block.

The confusion is this is NOT a factory car. The factory build comes from Ford. Then the car is shipped to Shelby, they replace factory parts and add tune just like any other after market shop. Plus we've seen pictures of them tuning the car on the chassis dyno which would give rwhp. However, with those numbers, I'm pretty sure they are quoting bhp using reverse match (adding in the loss) to inflate the number.

I saw this a little bit ago that Shelby ecoboost will have Jms boost max and pedelmax.

would the FR tune even be worth it since these cars pretty much need an aftermarket intercooler to hold any type of power? And in order to feel the true potential of the intercooler, we would need a tune anyways?

Here's what I pretty much come up with. People who are nervous or think that going with one of the two major tuners is going to cause a blown engine, then the FR tune is for that person. You get a little bit of umph and obviously some extra ponies. Now if you are serious about power, speed and fun, then a pro tune would be the way to go. If you have the FR tune, just expect to be eaten up if you go against a tune + car. Supporting mods are def a must, and the fmic is a good way to go no matter what u do. I just knkw from experience, you are always going to want more at some point, and I started off with an SCT tune and was happy for about a month. Curiosity led me to the AP and had I not made that decision, I would of never known how insanely fast these cars are. I'm at 36k now. Been tuned four different places since 1k. FBO and changing my oil and plugs prob more than I should, def prop help keep me in the safe zone. Good luck!
