Considering this thread is 4 years old I'm sure you know by now, but just for all future viewers of this thread: No, the GT350 and GT are not return style systems from the factory whatsoever. There...

My understanding of TQ+ torque source is based off my experience, which it only is seen during a rev-matched downshift. I have never seen it in any of my logs during an upshift and that's for all my...

Appreciate your response. That's about where I'm at, concluding it's false knock. Stock car and stock tune, anything I do does not change the situation. I've even cut all spark by 30% across every...

No clue what you're seeing in the editor that allowed you more low-end torque. Everything between an NA 3.5 and a 3.7 that I'm comparing is identical besides feed forward tables which are not even...

Could anyone shed some light on the relationship between Idle Airflow/Spark/RPM

Would increasing idle airflow affect idle spark, would it need to be increased or decreased in any way?
Does...

Disregard, knock issues still present. Only happening at low load, low RPM. Essentially right when the knock sensors turn on (35% load in the above log), it slams to max KR and immediately decays.

Update, pretty sure I figured it out. MAF could've been a little better even being a factory tune, but my idle air volume was a tad low. The car would "lug" just slightly when accelerating from a...

Hi y'all,

Weird car. 3.5 NA, not an ecoboost. Not a lot of parameters to log and maybe that's the big issue here. Can't even log inferred MAP or mapped points.

Here's my situation: completely...

Honestly the tune runs fine. I'm just picky and want it catered to me. I plan on having this car for an extremely long time and it's gonna be procharged. I want it as healthy as possible, especially...

After a ton of reading and comparing, this actually doesn't seem that bad. Seems all I do with my mods is turn off O2s, change volume size for the manifold to 12.5, change IMRC sensor voltages to the...

Alright I'm sure there's been a ton of these posts but it's worth a shot.

I just bought HPTuners with the motivation to read and learn how to tune my 2015 Mustang GT on my own. It's currently...
