Brenspeed is getting 40hp.
Here is what Brian said over at AFM
"Sorry for the delay everyone. It has been one rough week here at Brenspeed, but its finally Friday and I have some of the results. After dyno tuning 12 5.0's this week, we are confident to release hp gains to the public. I don't know how the weather was in your area but it has been miserablly hot in Indiana for the past several weeks and this week was no different. With dyno cell temps into the 90's and the car's coming in super hot from their drives, they still made amazing numbers. On average, we saw 40 hp gains on 93 octane and a CAI. These cars feel like a stage 1 Saleen or Whipple supercharged car above 3000 RPM. They just keep pulling and pulling. As far as the calibrations go, Brent set up the 5.0 to react the same as the 4.6 did with instant throttle response, more low end torque, more top end power, and better drivability all around. For the auto cars, he also increased the shift pressure and changed the shift schedule so it is a lot more fun to drive.
All 5.0 tunes purchased will be put into a special folder for automatic updates. Everything about these cars are new and as we learn new tricks or cool features, we will send them out to all current 5.0 tuning customers. We will be taking our 5.0's to the track once a week to put our tunes to the test and see if we can improve our product."

For the love of God, is it that hard to make as close to an apples to apples comparison on the SAME octane gas?
One tuner told me, 'because the cars come from the factory with 87 Octane and many of our customers will use 87 Octane, that is what we did our baseline on.'
BS
May in fact be true they come with 87 Octane, but what customer who is interested in MORE performance for their car is going to put the CRAP gas in that DECREASES their performance??
Nobody unless you are a complete idiot. Further, what sense does it make to say that and then give the customer a tune for 91 or 93 Octane if all they are going to do is put 87 Octane in the car? That would only ruin their engine.
Tuners padding the numbers like that to me just makes them seem fishy and untrustworthy (especially when they don't openly and publicly state that, but requires customers to probe to find the truth.)
Get on the honest wagon tuners, and do apples to apples same octane dyno testing from now on, k thanks.
Since 87 Octane to 93 Octane will produce about 10-15 hp all on it's own (stock ECU settings), I think it's pretty safe to say so far that most of the tunes, if done fairly on same octane gas seem to be producing in the 20-25 rwhp gain area.

I'm glad I'm not the only one who noticed that. Also, that is what American Racing Headers did. They took a baseline dyno with 87 octane. Then installed their headers and filled with 93 octane. I always read the fine print!

Makes sense
The guys I use said they would not do that and dyno with 93 before and after. That is why I bought their tune and also helps to get a great deal on an Intake!

+1 I agree, it's getting a bit ridiculous how the tuners are "playing" the numbers game with the 87 Octane baselines and then 93 Octane tuned.

It gets old seeing those type of comparisons

You get 10 hp from going from 87 to 91
I don't think anybody has actually tested to see if the ECU adjusts up past 91 octane and adds more power from 91 to 93 Octane. If it does, I'd guess based on past cars I've dynoed when going from 91-93 you'll get 3-4 rwhp more (or about 5 crank hp more).

Yes it is.
Hopefully enough of the tuners will see this "backlash" on the forums from tuning and then advertising like that, and make it right by doing baseline and tuned on the same octane gas from here on out.

I will say though the BBR tune and Steeda intake I have has really impressed me. I'm generally a skeptic and well to be honest the more seat time I have in my car the better it feels. I also think the intake looks great and sounds awesome.

On the topic of the Brenspeed tune, what is you guy's opinions on getting one if I already have an SCT tune I got when I bought my SCT tuner from my friend who is a dealer through them? Would you think it was worth it to pay $75 for another tune? I dont know how much better the Brenspeed tune would be compared to the canned SCT tune, MPG and Power wise. I really just like the tuner allowing me to set the RPM and speed limits and allowing me to clear codes (none so far thank god). Opinions?

This is from Brenspeed
"The 40 hp gains are going from 87 to 93 tune and the addition of a new intake. Over the past week we have had a lot of 5.0's on the dyno to further our custom tuning and to see if the 5.0's had as much variation in factory power as the 4.6 did and to make sure we did not get one of the factory freaks. Gains have been very good on all cars and we are very confident that our numbers are not out of the ordinary. While most cars were over 390 rwhp with and intake and tune, several were over 390 with just a tune.
I will see if I can get Brent to post some dyno graphs on the site for your viewing pleasure.
Ford did a awesome job designing these new engines and they are responding very well to aftermarket mods.
Feel free to call if you have any questions.

According to the SAE J1349 Test Results it was 404 bhp on 91 RON (Approximately 86 AKI) and 416 bhp 98 RON (Approximately 93 AKI). Ford says the car will get maximum performance on 91 AKI but the car was not certified on it.

If you want the business, just be honest!
