Aftermarket Tune

[ChitownStang]

I've had the tune for about a month now. Even with 91 octane (CA) I definitely tell a difference. I run both. For trips I run 91 and for the dragstrip i ran E85. E85 is pretty easy to get here. When I did data logging on the tuner the car was reading 78% ethanol so pretty good.

Sorry if I missed it, who is your tune from?

From everywhere I've read and even asked Lund owner, 93 tune is not worth it (8-10hp).

That's probably right, here they tuned Bullitt to around 430 rwhp as well. Which is about 10 hp from stock. But at least we get 30 hp since ours are detuned in stock

It ran 11.76 at 119 with just Flex Tune and drag radials. Wish I would have done a before and after to see the difference. Maybe next time.

Any Mach 1 owners tuned there cars yet?And if so,what where the results?
Have heard its not really worth the money tuning the Mach 1 due to very little performance gains.

Literally look at any Bullitt dyno over the last few years, same thing.

Steeda Tune is not released yet because of coding issues.
From everywhere I've read and even asked Lund owner, 93 tune is not worth it (8-10hp). E85 is totally worth it but a huge pain to find E85 and when you do, quality 70%+ E85 especially in the North is not easy to find. I don't want to have to test fuel all the time, plus 35% less gas mileage.
Headers make the interior way too loud for someone my age.
Think I may be stuck with stock tune for once in my life... lol

TuningByJames(makes the Steeda tunes) gets more than 8-10WHP from his tunes.

Matt at Steeda said they do the Tune in-house. Also their Video of one Mach 1 they did over a year ago showed only ~10hp.
Also Bullet tune is only for manual, no A10.

They also said the Bullitt Tune was "in house" in that James was flown there, and used their dyno. Its the EXACT same engine, it would be dumb to do another from scratch when all they need to do is add A10 management for the Auto. Likely just a Copy&Paste as the A10 is physically the same from the GT. They should already know that strategy they want.

From their own video the Bullitt picked up 22WHP/18WTQ Bullitt Mustang Baseline Dyno Test & Tune - YouTube

From what conversations I've had with Matt is that the CPU's have changed and they can't get their SCT tuners to read them properly. I think they need to change the Tuner they use to the same that PBD and Lund uses

Its likely an encryption change.

My understanding is Steeda tune is about 2 months out and only produces minimal gains.
Pretty impressed with mine compared to my 20 Gt 10r80,
Could never turn over tires on second gear shift in 20 Gt but my 21 Mach 1 10r80 does on 1/2 ,2/3 and occasionaly 3/4.
May just stick with factory tune this time unless I decide to go forced induction .
