Tune graphs with mods
so after installing XLR8 catback exhaust, xlr8 v2 jpipe, Rv6 HFPC these are my numbers. Graph with more HP is before install and tune of HFPC. Graph with more TQ is after install of HFPC.

he gains max torque at low RPM but then it dips back UNDER.
the graph is super jumpy below 4k RPM.
this is not good. he needs to get retuned to make the torque curve flat.
the way I can tell 4000 RPM is because the intake manifold butterfly opens up and you can see a rise in both HP and TQ.
this is a bad tune, OP.

The tune in the top is the most recent after the HFPC install. The torque number went up but HP drop by 3. The car feels better than after the first tune was done. Def stronger from low. I haven't really punched in yet but it feels good. I gained around 25 tq which isn't bad with all the mods. Could be better but still. The car feels good to me and gas mileage is up

the top graph shows something is wrong! you didnt gain peak torque. you gained max torque at like 2000 RPM then it falls off a cliff, dying...
below 4000 RPM, it's so jumpy! which you want a smooth flat torque curve. you dont want up's and down's like what you have
ALL my dynos of my J32 look exactly like your bottom graph. Very smooth torque and hp. never jagged up and down...the steep fall of the torque dips is what concerns me!
your power delivery was BETTER before you tuned it. smooth and linear

How much HP and torque do you think I should have? These guys work on even from exotics to evos etc so I'm sure he would know what he is doing, prob tuned to avoid reliability issues

is the first graph the dyno tune? Because its all jacked up. The car was more consistence before you "tuned it"...
He also used correction 5 smoothing on the chart. So they are really cheating
here my chart using SAE correction
here a friend j35a3 using standard correction also smooth 2

Before I did my research I was expecting 40 horses after everything but the torque take isn't that bad.

This is what he said.
The car shifted from 3rd to 4th gear right in that spot. It was graphed in RPM, rather than speed on the last dyno pull. Thats why you see that odd hump. Im sure you dont feel that thought. lol.
Like I said I do feel a little bit more power down low but it could use a Lil more pep.

Yea this needs a look over....... those numbers don't even look right either. And finding the right shop to tune your car takes some research as well. I seen some heartbreaks because of that.... How far are you from these guys? Innovative MotorWorks if your FWD the lowest I seen was 270HP... AFTER tune...

Where did you go for the tune? I live in Maryland also? And what Tune? is it Ktuner?
Are you on the Facebook group 4th Gen TL? Theres lots of folks from the DMV in that group than help with local shops.

So what should I do now? Take it back to 1st tune? Suggestions?
All dynos read differently. People on the forums are very ignorant to that. I dont understand what you are saying about engine braking and sound of the engine. There is no "enhance sound" or "enhance engine braking" parameters in the tuning. When we tune the cars, its very simple. We adjust fueling and ignition timing for supporting mods done. There is no magical buttons we press to change the dynamics of the car. Its just not possible. What you have now is fueling and ignition timing adjusted correctly for the modifications you have had done to your engine. Changing the tune back to the one for the previous parts combo probably won't help. But if thats what you want, I will do it.
Hopefully this sheds a little light on the subject. The internet is not always correct my friend.

This shows that you hit 248TQ at like 2000RPM..then TQ totally dips way below to 210TQ at 2500.
that's indicating something is wrong
it would make sense if you had a turbo to blow torque up at 2000 RPM, but you dont.
the dip is the part that is concerning. it shows you only achieve that 248feet/pound for like 1 second then it falls to 210, below stock levels...

Yes lease I hope he does so I can go back to Mike at Kinectic Autoworks and tell him this is what he needs to do to make it the way it should be after all those mods. Anyone that can help would be appreciated so I can know what to tell him t do before I make him switch it back to the tune before I installed HFPC. Cause if he does that I will not be getting any benefits from the install of the HFPC. I will but not what it should be like after the tune.

Dyno number can be different from shop to shop, but this is the same shop doing a before and after tune. If they overlay the graph they will see that something is wrong... sounds sketchy. Area under the curve also tanked if you overlay the charts.

your buddy obviously doesn't know what he is talking about.
IT SHIFTED GEARS RIGHT THERE!
Show me in the AFR plot where there is a "tune issue"

leave the base map as is.
I think I know why the graph look so off. The scaling is different. I over laid them and everything after 55mph looks pretty close except for the fact that you are not making any more power with the HFPC vs oem cats. They should have really used the same scaling

You just need to have them do it over again? Is this with Ktuner?
Just search for other Dynos threads with your mods and compare them and you will see the difference and also look for the one with the Ktuner if thats the tune you have. I am not aware of any other tunes out there other than that.
