Would anyone care to look at my logs and give me some insight. Just trying to stay reliable with decent power for a bit, anything helps ??

Tune definitely needs some love ?

Give this a try:

Switch to Map 2
Set FF to 25
These Duty Bias values:

duty_15	duty_20	duty_25	duty_30	duty_35	duty_40	duty_45	duty_50	duty_55	duty_60	duty_65	duty_70
50​	50​	50​	50​	50​	50​	50​	55​	60​	65​	65​	65​

Yeah just to add to this since the thread has been bumped:

MT cars are generally no problem to tune anymore. Have done 6-7 cars in the last month or so. The MT firmware and low WGDC method has worked well. Still not as easy as an AT car, but seems fairly repeatable.

Thanks @RyanA90 for reaching out to dial in your car! Glad we got it sorted quickly

NICE! Interested in some hard data on how the cars are performing tuned … any 1/4 mile 60-130 or Dyno numbers on any of these cars ??!

@Got_M let's see your 60-130 lol That's about as max-effort as a JB4 will go (E30+M1 meth)

I have posted a few dyno charts in this thread from folks running my custom maps, generally 435-440whp on 93 octane, and 465-470whp on E20-25ish. Ultimately, it is only the gains over stock that matter since dyno's vary too much to be useful.

Sadly, no MTs on the dyno yet, but just finished @RyanA90 's tune and he plans to. (91/E25 fuel)

I'm planning to go back in the next few weeks to the same Mustang Dyno I went to when I only had DP/Intake/91 (400whp/410wtq) for consistency.

Did these 2 runs on low fuel tank with those settings, not sure if that makes a difference but will try again tomorrow on full tank. Also already have boost safety on 23.0, noticed I still got 23.40 in one of the runs ?

I will get some dragy numbers this weekend since we turned up a bit more... I'm guessing 8.0-8.2ish but maybe in the high 7's with less weight. Might take the seat out and run less fuel. If we can make 25-26psi it might surprise even more people.

managed to get 3 more runs on full tank and I think it looks worst, timing all over the place ?

It honestly doesn't look too bad, but yeah probably need to dial off boost a little.

Try this map 6 out. Remember to set FF back to 25

map6_15	map6_20	map6_25	map6_30	map6_35	map6_40	map6_45	map6_50	map6_55	map6_60	map6_65	map6_70
0.6​	1.1​	1.6​	2.1​	2.6​	3.1​	3.6​	3.6​	3.1​	2.6​	2.1​	2.1​

Subscribed. I was considering JB4 and Fuel It when I got my Supra but I saw MTs were having difficulty being dialed in. I need to read this entire thread now lol

Making some steam now. Hitting 24psi stock turbo, JB4, charge pipe meth, intake, catted downpipe. Thanks @ColonelAdama

Alright managed to get 3 runs in on the way back from work on map6 with these values set and FF on 25.

Looks great!! Good spot to keep it. Seems like all you can get out of the current fuel.
