Just went FBO on my gen 1 coyote. Made 440whp and 387tq. Doing e85 next. That torque number that your car made is impressive

[@nateonfireball]

Josh Rolfe he’ll make alot of torque by comparison due to direct injection and higher compression

[@garlanddavis8160]

I live here in Baytown and just discovered your channel... Surprised it's taken me this long haha... Good shit man!! Got a local guy here in town as well who is actually tuned by Matt ... I believe he's around 500 also. I'm going PMAS, also got a local guy who designed a turbo setup for my old truck who is setting up some headers for me, and currently have a custom 3in. Catback... I will be using Ken Osborne with OZ tuning to dial it all in... I'm pumped to see the final numbers!

Great video! Those numbers are impressive. Only saw the flex fuel numbers at this point. 🏁 🇺🇸

[@Zander13Productions]

crazy how much these cars make with light bolt ons. those are strong numbers

[@jasonmcquinn6601]

Glad to see the car did so well. What mount do you have the ngauge in?

[@therealdyl13]

mine was the same way. I had to drive around for a little bit for the fuel to read properly. after it read properly the e85r had more timing than the flex fuel tune.

[@TheCdM1981]

I would like to see a dyno with stock exhaust and Corsa exhaust. I have a feeling that $2200 exhaust adds less than 5hp. Just curious though.

[@josesilva9203]

What an awesome mustang, I’ve been undecided with this car and the challenger. What trim level or body style is this one?

[@kf9559]

Man that's some good power for just bolt ons

[@chrisknight3681]

If I understand Lund correctly the flex fuel tune is using a combo of pump gas with ethanol mixed in. e85 is just that and e85r should have a higher content of ethanol.

[@hialeahhigh]

Best thing to do is data log that E85r tune and get it dialed in. Thats the best tune to use while on e85

[@a.wheeler7731]

Interested in seeing what they say about the logs for the e85r tune, and if they have an explanation about why it made less on that tune.

[@dantheman9569]

Yes I love long videos

[@Bigmed9]

[@johnnykilroy9399]

RP Productions man you should take a look at R/T Lifes video of a stock scat pack putting 430-445 rwhp on the dyno. And srt.b5 of his stock scat doing a 11.52 with only taking the seats out.

[@devinwang1603]

did you get a revision for the e85r tune? i can only imagine it would be the same as the flex if corrected

[@Mart10_]

Kyle seems like the coolest of the squad. Has he ever dynoed his gt500?

[@rynev3392]

The E85r numbers seem more accurate, considering that was a mustang dyno

[@TheHardestArtist707]

What's up with e85? Does running e85 require a tune first on 2018+ GT 5.0?? Can you mix with 91 Octane? Or does the tank absolutely have to be emptied out?

[@pops55650]

You could hear the car pull harder the first run. I could tell the second run wasn’t as good just be listening. You should have ran another synopsis run after you switched back to the flex tune.. did you? Maybe the motor was heat soaked after your first run? Let us know what your tuner says after he looks at your data logs. Sounds real good though!

[@pops55650]

I hate spell check after reading my last post lol

[@erikthered1975]

How much e85 was actually in your tank? You may have said it but I skipped some of the video. Maybe without the reg residual fuel in your tank the e85r tube would respond better

[@talibsunesara8708]

New car...surprise surprise

[@patriot2118]

Can you tell the difference between e85r and flex tune? Which is faster?

[@moose5.9]

It's not really insane to think a brand new car that's DOHC makes more power than push rod technology from decades ago with some simple mods. Solid runs though

[@tyrelramage3472]

Did lund fix the e85r tune? And if so did you gain any more power from it?

The stainless works quiet mufflers have flow issues too btw, not sure if thats the model he has on the V. Race proven motorsports has a video showing the stainless work mufflers took away like 80 hp due to bad flow.

[@Fallsmuddin]

A. Wheeler that was the quieter mufflers. They gained back to normal with the louder mufflers which I have.

[@RedHaloManiac95]

Here we are in 2022 and the 3rd Gen coyote is really shining. 850hp on a stock motor, absolutely nothing needed to put a blower on, 10 speed still kills and with just bolt ons you’re in the 500’s easily

[@dennisrobinson8008]

Back in the original 5.0 days we thought 350-360rwtq with the long runner cobra intake was a really high number out of 302 cubic inches. The shorter runner victor 5.0 could make more high end power but reduced torque. It's crazy that the DOHC is making a rwtq that a well build 350 would do.

What would headers and e85 be in a manual?

[@Adrian5oh]

[@newfinishautospa]

Should have ran the e85r tune again after some octane booster. In my experience, the alcohol learning process has some error, give or take a few percentage points. You could have had e80 in the car and not e84.7. If it’s pulling timing then it’s most likely octane related.

[@dennisrobinson8008]

Does anyone have gen 3 coyote cyllinder head flow numbers? I have like 289CFM@.500" lift, but that's the same number that was around for gen 1 and gen 2. I have to believe part of the power gain was improved cyllinder head flow and it would be higher than that.

Friend, how much did you spend just with the headers, catback and CAI thinking about buying an s550 soon thanks brother -from Houston, Tx 🙂

[@byoung1991]

I don't know if you ever got an answer to your question but the headers are around $1,100 the CAI is about $400 and the catback is around $1,500. So around $3,000 I would guess plus the installs so maybe $3,500

[@Dude-tb8ry]

On American muscle headers run for $1,500-1,800, catback, $1,500-$1,650, tune & intake bundle, $950. Not including labor cost or a good set of tires to put the power to the ground.
