Awesome, looking forward to the updated dyno sheets!

Do you plan on dragging the car? Would love to see some 1/4 mile slips!

My bad! Been crazy busy and haven't checked the forum in awhile.

The tune is still absolutely amazing. Thing pulls so hard all the way from 3k to redline, and the boost is strong at 14-15psi throughout. The logs we captured were perfect, and the tune is extremely safe/reliable.

With that, our dyno showed a delta of 44whp/44wtq (on a Mustang dyno). We can probably go more aggressive, but it feels so good that I plan on leaving it as is for now.

I will post up a full review as soon as I can get updated 0-60 numbers. However, stock 0-60 was 4.7 seconds, after the tune, I was able to get 4.1 seconds.

Overall, the guys at ACF, and the product itself, are absolutely great. Highly recommend them!

Thanks for posting your results!

The 44whp delta is vs your stock setup or previous tune? Is this a "stage 1" flash?

How does the tune effect downshifting. When I'm cruising at highway speeds in 6th and then want to punch it I'll rev-match down into 4th and then go. Have you tried anything similar after getting the tune?

Does the car behave differently in comfort aka wifie mode? I want to be sure that I can still putt around town when I have the wife and kiddos with me.

The delta is between my stock setup (Sport Cat, AFE Intake) and then the flash. No tune beforehand

That sounds about right if I absolutely want to punch it on the highway. It just does it much faster haha.

No difference in comfort mode since we have the multi map setup where Comfort mode is still the stock tune.

Sweet. I wonder if they could do a tiny bump in comfort mode or at least have the throttle response be closer to sport or sport+.

delta should be at LEAST 70whp especially with a Sport Cat regardless of Dyno

Your source for this 70whp delta is?

Even Luminous first Enzo flash had a delta of 90whp, but that was Stock vs. Tune + FBO. Who knows what the delta would have been FBO vs. FBO + Tune. A lot less than 70 is my guess. (sorry to keep bringing you into these discussions, you are the only one that had a similar setup/dyno history)

A few additional things...I have not posted logs or my dyno sheet yet, so once you see that, numbers aren't going to provide the whole story. Secondly, we are still on a mild tune, and are going more aggressive within the next week or so.

We could stay at what we are today and I would still be unbelievably happy with it, it is a beast. But, as everyone knows, numbers apparently rule all, so we will get higher to appease that crowd.

I believe that in Comfort, there isn't much you can do about throttle response. However, we upped the response in Sport/+. I'll defer to ACF for this.

Mind sharing some logs?

I keep hearing from another guy how great ACF is but I still can't find a proper dyno result yet 1/4 mile slip which explains if the flash is really great.

It'd be interesting if someone went from the AA8 tune to the ACF ecu tune. I'm thinking of going AA8 as my stop-gap until I do an ecu tune.
