VelocityAP Jaguar F-Type ECU Tuning, V6, V6S, V8S, V8R
This has become our Waiting for Godot.
In addition to the -1.5 mm upper pulley, I have now installed the lower +18mm lower pulley. The lower pulley added an additional 25 lb-ft of torque @ 4000 rpm (now 430 at the crank), but its throwing an "out of expected parameter" code at 6100 rpm. The computer doesn't expect to see anything over 18.7 lbs of boost. Velocity AP has created a tune to resolve that issue and to take fuller advantage of the. boost. That will go on the car on Monday when I get back from travel. I hope to schedule it onto the dyno for next Friday if the code issue has been resolved.

I must have missed that email. I had some isssues while travelling overseas, not all my emails came through. If you could resend it that would be great, and cc Tuning@VelocityAP.com as he'll be the one you need to co-ordinate with.

Me neither. Unfortunately, my dyno shop is now in the process of moving and I won't get on the dyno until July 15.
I'm going to wait for the long-tube headers to go on with the sport cats.

Yes, I have a stock run. Almost identical to the factory claim. You can find that run in the "V6S Tune" thread.
Which engine do you have? Jag's specs are fairly accurate. You can use that information along with a .85 drivetrain efficiency to calculate a correction factor for that dyno.
I have the R, I actually took it to 3 different dynos and I got 500whp in all of them though
Dynos are tuning tools only. The only thing that matters is before and after gains on the same car under the same conditions. True performance is measured by trap speed in the quarter mile. There are way too many variables to compare one F Type to another on different dynos under different conditions.
