Wolf tickets b. let me see dyno graph. 405 hahahahahaha with a tune suuuuureeeee
Whys that so unbelievable? Cold air intake and quality 93 octane tune with 93 octane in the tank adds more then you think ask anyone who tunes these cars. I'll get you the Dyno graph when I find it . Check out this article.. Lund http://www.*******************/2014/12/09/tech-2015-mustang-cai-tuning/ended up with 408 after JLT cold air and tune only. .. these coyotes 2015 and up have real good flowing cylinder heads , actually from boss 302 from previous gen. so any changes to the intake at all add a lot of power as long as it's tuned properly. Revolution automotive with JLT cold air and tune only ran 11.8 in quarter mile , tires were slicks and skinnies

That's not "tune and intake only". Slicks and skinnies vastly reduces unsprung weight, increases traction and weight transfer. Easily $1,500 in wheels and tires.

My Steeda CAI and 93 tune put down 414/382 SAE in the summer. Now with Sniper, stainless power headers and 90mm TB and e70 it put down 450/380 SAE.

That is tune and intake only.... Tires don't add power. We're talking about power here buddy. 408 is what Lund made , I made 405 with that same Lund tune and steeda cold air . And now I'm making 440 rwhp on E85 with only addition being gt350 intake manifold... Tell me that's impossible too cause that's what everyone else is making as well. Throw headers and I'll be making closer to 470

You cited a 1/4 mile time..I was disputing the time obtained, not the power put down.

Ummmm...no you won't. You won't be close to 470rwhp with a GT350IM and adding headers. Outside of a happy ass dyno, you aren't getting that.

We just did a dyno day last weekend with 3 GT350IM cars with headers and tuned by Lund. Highest was 441RWHP. 2 others were in the low 430s.

I made 444 rwhp on a mustang dyno with no headers tuned by aed, not saying I'd make 470 rwhp with headers, but I wouldn't say it's out of the question

A buddy of mine with FBO AED 93 tune put down 420 whp 396 lbft on a mustang dyno but 397 whp and 372 lbft on a dyno jet at flp performance dyno. Same flp dynojet different day my car with only Lund Flex tune on 93 octane, mishimoto tube, afe filter, x pipe borla catback put down 404 whp 375 lbft.

Even the cars behave different on modes, from the factory they all put down different numbers to begin with. It is so bizarre!

Not being an ass but...do you really believe you made 444 on a mustang dyno, no headers and tune only? Please tell me no...please. Mustang dynos read lower vs dyno jets. That's a known fact, too.

That's 26 rwhp away from stock GT350s. You have no headers, no intake manifold yet, you make as much power with people that have those mods.


Now...using X dyno as a tuning tool to track your before and after numbers while doing mods, that's great.

Ok yes I do believe I made that power.....

Mods are gt350 intake manifold, gt350 throttle body, jlt cold air intake, 47 lb injectors, e85, mbrp cat back, and....... NO HEADERS. AED TUNE

The way I meant for my comment to be is no headers meaning I have everything else..

Todd depending on the mustang dyno it is possible. Let me ask Demon Coyote so he can post his mustang dyno results. He told me he put down 420 whp on a mustang dyno in Chicago versus the one we both used at FLP in Naperville. My guess is those dynos need recalibration. On that mustang dyno i bet your car will put down 460 + whp. He only had stock manifold and 93 octane!
