Well, I am currently TDY for the Air Force in O'Fallon, Illinois. I needed my car tuned after removing my SAFCII and installing a VAFCII and SSIM. I honestly didn't realize that the shop I scheduled with had a Mustang Dyno. So, I told myself that the numbers were going to be lower after reading all the info on here even though some info here says that they read higher. All I got from them was some dyno sheets and I am in a hotel right now so I cannot scan them but will tomorrow at work. The highest numbers I pulled were 236whp and 233wtq. Compared to 248whp/248wtq on a dynojet that I pulled last April without the VAFCII and SSIM tells me two things.....

1-Mustang Dynos definitely read lower than Dynojets

OR......

2-Maybe the Mustang dyno numbers are correct and if they are then 236whp and 233wtqmakes my car pull a SH!@LOAD harder than 248whp/248wtq ever did.

MODS...

So tomorrow I will try to get the papers scanned and put on here. If I cannot do that then I will go to a dynojet dyno and see the difference hopefully this weekend if I can find one around here. Just to cover my dyno tracks, I did pull 240whp/239wtq in November in OK City on a dynojet. More to come on this...

mustang dyno #'s are lower than dynojets...I read up a lot about this. That probably explains why your car is pulling harder than it did before with the "higher" numbers on the dynojet.

Im kinda new to this but did the shop tune the VAFC in open loop or wide thr? Also, what kind of headers are these?

That is true to some extent. But what it comes down to is how they set up your vehicles parameters/attributes.

If they used the correct parameters for your car, then yes, they will be somewhat lower than a DJ, but if they do not set your car up correctly, the values could be much higher.


Nice numbers BTW, any idea on what values they used for your vehicle (COF)?

Nice numbers man, just to clarify this is the same exact shop that I am going to today to drop my car off. I hope I hit at least within 5hp of this. And Then what I'm doing is going to a shop with a dynojet after I get the car tuned to see what numbers I'm really putting out...
