hey lschiavo hows ur gas mileage? horrible? or not bad? i wanna know if its gonna eat a lot

 

about 15 miles per tank less than before

 

They charged you 5hrs worth of dynotuning and you came out with the exact map I posted with no changes?!
I'm almost sure that "metallic sound" is detonation.

 

this crosses at 6K

I guess with turbo everything changes

 

Nope. Its a mathematical formula not dependent on aspiration. HP=TQ*RPM/5250. Therefore, when RPM=5250 HP=TQ (when using HP and Ft-lbs)

Seems to indicate that something is wrong with the dyno.....

 

then i really don;t know what's going on..

 

Why did you pay them when they clearly must not have tuned it right? If I understand you correctly you made 245hp on the dyno, but you discarded that map because it didn't run well on the street and are now using your original map giving you 188hp. Is this right?

 

Also, check your "additional injector map" and see if they added extra lines for the higher boost. If I remember correctly, my 0707 map only went up to 53kPa (7.7psi) since I wasn't going above 6.5psi then.

 

With the 07-07 at 8 psi i am making 240 WHP. Ask me how? i dont know

 

There's clearly something wrong with their dyno since Torque doesn't equal Horsepower at 5252 RPM. But as long as you can feel the difference, that's what matters. Looking forward to some GTech times to really compare the difference.

 

Do you know what your a/f ratio's are? You will likely be lean if you are running the original Greddy map and are at 8 psi. Did they still charge you even though they didn't do anything?

 

its not the dyno itsthe chart- the 2 y axis' are not to the same scale. just need to fix the T scale

 

That's for the 2nd dyno he posted.
The 1st dyno posted, showing the 245whp, does have the y-axis on the same scale and they cross at 4,800rpm.

 

Ok found the problem. it is a computer graph problem. I compared my best run (245WHP and 217 tq) vs another run, and in this graph my best run crosses at 5200. It is the same run just comparing to another one. Dont know what happened, this is Stock boost vs. 8 psi

 

I feel better now

I want a ride!

 

I'd bet you are running dangerously lean at the higher boost. Since the stock map doesn't go that high, you might be minus one injector per rotor!

 

lschiavo,
looks very good, hope you can figure out the high rev issue. 15 hp and 30lbs of torque on a tune, wow!!!!

also with that much torque down low it must be fun.

beers

 

fwiw, I believe if you had 8% 'correction' your car really put down about 265hp - on a mustang dyno no less...figure, 280whp? on a typical dynojet?

:D

 

As has been said before, you've got to be near hitting the wall on the OEM injectors.

Still, those are awesome numbers!

 

yeah dmp i sright- the corrction is just to be able to make a comparison against people dynoing other places. but what is said before the correction is what you ACTUALLY MADE on THAT RUN. very nice i bet close to 280 as well.
