100 HP gains on a 91 TUNE !

[WildHorse]

I could see 100 hp gain. First pull was on 87 octane with stock tune pulling timing, second was on e85 with different weather info input on the dyno.

Clearly says 91 octane. At 1000 rpm lower than factory peak rpm.

I figured if they're willing to stretch the numbers a little, they'd be willing to also stretch what fuel they're using.

Tuned for Methanol with 10% Nitro should get you there.

482/466?

Definitely not a dynojet. For what it's worth, if you race, NASA will only allow Dynojet for RWD's, and AWD/FWD can do one of the others as well, but they get a 1.1x penalty. Perhaps this is on one of those others that would overstate your hp by 10%... so taking that into account, it's a much more believable 434/419, which is probably a touch more than what a stock Bullitt does. How a "480hp" car does 387/363 stock on any dyno outside of Mt. Everest is beyond me.

If not, for comparison, with my stock 2018GT being around 415rwhp, I only got 50rwhp from long tubes, full exhaust, and e85 race tune. So, they're doing that with a Bullitt (what, another 10rwhp?) and on 91? I'd love to see what the advance, afr, and fuel trims look like.

Which is what makes it so silly. Everything on the gen 3 and especially the Bullitt is set up for top end power

this is like thatdudeinblue who made "460rwhp" on his bone stock 10a 2018 lol some dynos are really happy (miscalibrated)

Yea I was going to tell him that, but didn't want to start an argument.

its funny with these videos. As someone with dyno experience, you can make a dyno say whatever you want, BUT WHY? it never does you good especially in the days of the internet.

It can be helpful for business to the dyno operator/tuner, who wants to appear as if their tunes make more power than the competition’s tunes. I’m sure that’s happened many times over, but it sure is a very unethical way to do business. It’s somebody’s way, but definitely not the true American way to do business. I wasn’t bent when my car didn’t make 500 whp on the dyno. I’d rather know actual numbers and more importantly, that the tune is spot on and safe.

thats what im saying, to portray it like that imo is unethical. youre essentially lying to your customer base. WHY? its not like there isnt some other dyno in town or locally that could be visited
