Hey guys,

I went to the dyno today with my first shelby 500 customer. He has a black convertiable.

We started out at 421 rwhp / 408 rwtq.

The first tune with the SCT baseline file made 438 rwhp / 421 rwtq, a nice gain of 17 rwhp / 13 rwtq over stock

Next I made some adjustments of my own and made 458 rwhp / 437 rwtq, up 20 rwhp / 16 rwtq over the SCT baseline and 37 rwhp / 29 rwtq over stock.

Finally I made just a few more changes with some timing as the a/f was perfect and ended up with 464 rwhp / 444 rwtq, 43 rwhp / 36 rwtq gain over stock.

The best thing is at different points throughout the RPM band it had gains of 50 rwhp and 50 rwtq. We could have waited 30-45 minutes and/or iced the supercharger but I wanted to see what it would make with minor cool down periods, mainly the time to make a tune and load it in the car. It was very cool though and if this car had an intake and a pulley swap, 550+ would be easily made...

Not to mention though when he drove the car afterwards he loved the new throttle responce from the BamaChips tune, I did make some adjustments to the throttle to reduce the low speed delays, not enough to make it surge while driving but just enough to make it even more fun to drive!



Here are some photo's of the car and the dyno sheets....

Thanks, Doug.

 

congrat`s and i am sure you had some fun.........now lets see how much we can squezze out of these gt`s here........push it as far as we can go...

 

There is NO throttle delay/lag with the new silver oak processor. This ECU is 10X faster the Spanish oak processor found in the 05 and up Mustang V6 and GT! Ford will actually be switching to the silver oak processor for the 2009 Mustang GT!

 

Thats awesome Doug...

 

My customer was happy with the new found low end responce from my throttle adjustments. I never drove the car as I didn't need to, the customer was the one who knew how it felt both before and after. As with all of my tunes I worked heavly on the DBW settings to further the overall driveability and feel of the car, heck he even asked me if I did something with the shifting because it was so much smoother under normal driving, of course for an manual I couldn't but I was able to smooth out some of the tables.



Thanks, Doug.

 

Very cool Doug, nice job with your first Shelby!

 

ECU speed is not the cause of the throttle lag.

 

Yes, there is no throttle lag on the GT500 --- and Doug, the shifting in this Beast is and issue with regards to normal streeting - mine always wants to rap out as soon as you begin to engage the clutch.

Looking forward to seeing how the Tune evolves for this car.

Great numbers.
