Not sure where to share this post so Mods please move it if needed.

It was through this forum that made me choose Tony's products. Thanks again Tony for the awesome customer service and top quality system.

Got my car tuned by Jtranstudios here in Houston.

It was a 78 degree weather on a mustang dyno.

Baseline was 316 whp and 252 wtq

After tune came out to 332 whp and 252 wtq

Mods: Stillen Gen3, Motordyne, Art pipes, M370, E370

6MT

G37s Uprev Tune by JtranStudios - YouTube

Torque came out exactly the same?

Yeah it was something about when he try to get more torque out of it, it messess with the timing. Overall, I'm still happy with the outcome.

Were all those parts installed when you did your baseline? Something's not adding up. That dyno's a heartbreaker, so the HP looks good.

Yeah it was already installed. I didnt do a stock baseline dyno. Even the other G's I went with same day that had exact same mods had little to no torque gains and mostly hp gains only.

My friend's 5AT put out 302 whp 233 wtq after tune. Same exact mods as mine in every single bolt ons.

Ok, that makes more sense that the change is due to a tune only.

Btw, how's your GTM holding up? I almost got into the GB Sam set up for the TT kit. Kinda kicking myself for not doing it. Lol

Still going strong. GTM makes good stuff.

If torque stays the same but peak hp is higher that means your torque is peaking later in the rpm band.

You should compare the torque at say 3500 before and after as that will more accurately reflect the improvement in drive ability.

I just thought it was odd it hit the exact same torque number before and after.

He didn't include the highest tuned plot on the graph but doesn't bother since its just peak number. As you can see, the gain from the tune comes around 5k RPM.

FINALLY! someone who has almost the same mods I will have!! haha the only difference is instead of the motordyne exhaust im doing the aam s line mid pipe and short tails. im hoping to get around the same on the dyno, but we will see!

I am leaning torwards something along the lines of the aam short tails, hope to see dyno of that setup.

OP: nice numbers.

Oh as soon as I order the exhaust and take it to Z1 for the dyno ill post results when I get to my hotel in ATL! Haha

thanks


recently added aluminum driveshaft. Love it..

So my car now feels what a stock 370z feels like since yall are a lot lighter.. hahah

Our drive shaft is Carbon fiber IIRC. The G isn't?

nice! im thinkin of getting my tuned from them as well

yes.


Do it. My friend was setting up a group tune like he did for us. IDK if that fell through since last I heard nobody signed up
