The car feels very good. I like it.
I will send the dyno sheets shortly.

Those are the dyno sheet advice,

I think that you are just fine. Did you have an uprev tune done? If not, that will really help smooth out everything and get a few more horses too.

Dyno looks fine to me , don't worry your car doing great.

Thanks guys.
You are really saved me. ��

I think i saw you car couple of days back at 3atif workshop .

aalqaedi · 07-22-2012, 08:11 AM

Yes I went there for installing the intake manifold and the test pipe

Gaining 30whp from a tune is telling me something is still not 100%. Most gain 10-15 from tunes. Were you able to see the A/F chart?. I don't see you making any less than 300whp on any dyno with the mods you have. Your torque curve doesn't look like other VQ motors either. The torque looks weaker than normal below 3k rpm. One good thing to mention is your car definitely wasn't running out of breath at redline, still looks like it was pulling.

A mustang dyno is what I had mine tuned and got 275 whp and it runs really well. There has always been a large difference between a Mustang and DynoJet. His car on a DynoJet would show 300-310 whp just like mine would show 310-320 easily. That's why most people look for the DynoJet to get the numbers. I just look for a good curve and the peaks where I use it. You can feel if the power is there. My last car was pushing 550 whp on the DynoJet. His chart looks good, but I think some better tuning could be done to smooth out that torque curve.

If that is the case the numbers should be similar to yours. He has stillen headers, but no pulley. It could be the extreme heat out there as well. I generally measure a mustang do as 6-8% lower than dynojets. It's just a rule of thumb for me. I do feel though if the OP has the means to reverify the tune and dyno.

OP doesn't have the pulley, his exhaust is more restrictive and I doubt he got a good tune by the looks of the torque curve being so jagged. Also you are correct about the environmental factors too. A better tune would come closer to matching my numbers.

I agree with SShawk, I was 298 on a mustang, With stock cats and only a catback and Stillen Gen 3's. I know Dynos are different but 30WHP, The mustang I was on was a "Heartbreaker dyno).. An did I see that right 211 WTRQ? I was 240, An Auto X Coupe, What gear where you in 5th right?

aalqaedi · 07-24-2012, 05:59 AM

Hi guys,
as a tuner they are good but they are the only ones in my city. About the weather it is very cold here

it is about 45c to 47c and very humid also.
I will try to do a Compression test to just see if there are any problem.
I drove the car it is different from before. especially when driving with the (tiptronic.
I having problem with the test pipe noise not the hissing sound but it is like the pipe is touching something. I will take it back and recheck the installation.
Thanks bro's

there is also extreme performance in abu dhabi who does uprev tune in case you want another option. Tensai seem to good for the Evo,scoobies crowd but not for vq engines.

Will give them a try thanks bro
