This is my question too. Lethal has video on YouTube getting 525rwhp well over 600 at the block. Yet as I watch dynotune numbers at most shops headers + dynotune tune is neting more like 450rwhp. That's with the upgrades such as core and heat exchanger.
I'd like to know how they are squeezing an extra 50-75hp.
I'm going to call them Monday and ask them what pully they are using. I know there is a smaller pully option but the lethal video didn't state that was the case. If everything is equal I'd like to know what success or issues have customers had with that tune and small pully if in fact that is the setup they are running in the video.
75hp extra is a lot left on the table...

Ford racing probably put a couple million dollars and thousands of hours into tuning the pcm programming for the whipple supercharger, aftermarket really can't compete with that, but they can give you more freedom with the tune to change it up, whereas ford racing has their pcms encrypted more than the stock ones to prevent messing with the tune, and getting the ford racing pcm sounds like it is more expensive and takes longer than having a shop do the tune
I don't think I agree with that. The dyno is a tuning tool so to accommodate additional mods and conditions. I doubt Ford could come up with a one stop tune that will make more power than a good tuner looking at numbers on a dyno then having the ability to retune until max power is made.

I'm sure any tuner could do it if they had the same amount of time and money to devote to that one vehicle, but it's extremely rare for a shop to have that much time for one vehicle

Has anyone had any issues with their blocks or anything with a supercharger installed? Are the tunes really conservative to protect the engine?

Ford racing dyno tunes everything they make, I didn't mean they spent thousands of hours sitting at a computer looking at simulations and tuning it through a computer program, I'm talking about them spending thousands of hour on the dyno working out all the little flaws to have maximum reliability as well as maximum power, this is where aftermarket falls short, they have the time to get maximum reliability with good power, maximum power with poor reliability, or somewhere in the middle, I'm not ******** on livernois, they make awesome products, and I'm sure their tune is better than some of the other ones out there, but you can't expect them to be better than a multi-billion dollar company that has money to blow and time to throw away on tuning
You completely missed my point

again your having your own conversation... If you have a moded motor truck you need a custom tune. Period... For example Ford does not have a tune for head cam blower application or any combination outside of long tubes and that's through whipple.

I think you missed the point of my original post, you were criticizing livernois for not making the same amount of power as the tune through Whipple/ford racing or lethal performance, and I brought up one possible conclusion as to why they aren't, it's very likely that the livernois tune has much better reliability than the lethal tune
