I got my car tuned recently on a Mustang Dyno (2003, 70k,93 oct, 25 max boost, 95 F) and i am wondering two things:
1) Does the TQ come on TOO quick and too late? Granted i am almost stock so it cant be that dangerous ( i have TBE (HFC),LICP, MBC, 18 PSI FP WG,9 BOV) but still, the curve seems a bit steep.

2) Why does the TQ drop off so quick? Is is the tune or do i need to upgrade something? My car us running fine other wise, 14-15 A/F on idle and 11 WOT.

Thanks!

PS: Sorry for the crappy pic, the tuners printer sucked.

 

TQ does seem weird.

get tunned by Jestr tunning or TTP engineering, tell him Andy sent you

 

After 6000 it is dropping too quick. Could be mechanical or in the tune.

 

It does seem to fall off pretty fast, kinda hard to say what it could be though without actually having someone look at your tune because that would help rule out or rule in a mechanical issue.

Looks pretty typical of a stock turbo tho. Im no pro really with this stuff, but based on how many peaks and whatnot there are on the graph, it looks like it could be a tuning issue. Anyone agree?

 

...

Notice that the seemingly drastically fallen torque is still 208ft-lb at redline - the engine is still making 285whp.

Whoever set that graph up should be shot.

Look at the numbers indicating the torque and horsepower range. They don't start at zero like they should.

If that wasn't bad enough, they don't even start at the same ****ing points.

Torque starts at 198 and maxes at 303. So, yeah, your torque appears to have a huge spike getting like 1000% bigger, but it really only went up by 50%.

cliff notes: That graph is misleading, your car is fine.

 

Do you still have the 9.8 hotside on the turbo? You can switch to the 10.5 hotside.
If you can post the boost plot along with this. I think its just a weak tune on the top end and boost taper, even with your wastegate.
The dip at 6400rpm is not normal. On stock cams and stock turbo the torque drops on the top end, but not as sharp as your tune. Maybe its knocking on up top too...

 

Agreed. CFT sucks at tuning evos and they change their dyno to read higher or lower depending on if they are tuning in house or an outsider is tuning. You are probably making less power then when you went in there. Take it to the track and you will know for sure by trap speed. If its slower, then youre making less power.

The car looks like it is detonating on the top end. Power should not go up and down near redline. Its probably pulling timing.

 

Its funny that a few people are mentioning the TTP tune. I had Scott tune me the 1st time and it was terrible. It turned out to be way to rich.
Long story short, i went to CFT because thats where Scott tuned me and that was the only place i knew of after he moved his shop and didnt let me know when i showed up at his doorstep.

With his tune i was making 252, ( i also didnt have the WG to be fair) and when i told him this seemed low, he basically told me, it is what it is, instead of doing a boost leak test or telling me what i need to do to fix it.

Here is my prior post:

Old dyno sheet , half way down the page.

Ill probably have to make the trip down to AWD to get the job done right, since i am getting cammed next.

 

Another option would be to come visit me in Jacksonville... let me know if I can help...

 

Here is an old graph of mine on my tune with the stock turbo. You can see that it should hold power up top. There is no reason for your sharp decrease in power above 6000rpm.

It not going to blame the tune, because tuners catch the slack every time a car has a problem which is weak, but this just doesn't look right.
