+3, +2, +1 ...holy crap...just got notified from DHL...package is there...teeheeee...I am so giddy!!!
Contemplating heading home.
...so this will be an unboxing and detailed write up of the Velocity AP tune with dyno results posted for before, and after on a XF 3.0L Supercharged engine (Ford sourced). Stay tuned...haha get it
Takes alot for me to do the pee-pee dance nowdays....

a pretty box...and some stickers...(I love stickers...reminds of the sticker filled windows of my youth...dam..am I ever going to outgrow this ****!)
some cords....
...and...le boite magique ... in which Velocity will deliver tasty, tuned HP
The initial dyno was done at Eurocharged in Austin. At the time it was stock, with the exception of the K&N Filters:
...and the dyno results:
Now...for the mods. At the moment, the cat is breathing through a set of K&N filters going into a TCP Intake. It blows out stock headers down into a resonator delete and X pipe, and sounds off through a pair of dual active exhaust mufflers from Varex (I want the fighter jet tips from Paramount!!...is that too much?).
I am seriously think of finding a dyno closer to home rather than drive down to Austin to run on the same dyno. If anyone has any suggestions for places in the Dallas area let me know. I would love to order the front splitter from Mina if they would ever get around to sending me a picture of the dam thing. I am getting the XFR rear valence diffuser carbon wrapped. Then I will look into a "black pack" solution for the window chrome. Not going to spend money for the OEM black pack as I would rather put $1200 into a ALP jammer. The final piece will be a lower crank pulley, if I can find a place that will R&R for a fair price.
I plan to do the tune later this week when I have time. I actually have just been victimized by dirty sticky fingered vandals (just like the Jag factory) who took a $900 piece of electronics from my desk at work. Left it there for a few hours, and like magic, it grew little legs and just walked on out the door.

I would definitely use the same dyno as before so you have some idea of any improvement you get from the modifications.
This!!!
Switching to a different dyno for the after run will skew the results, especially since the numbers from the before run seem a little optimistic, no offence mate.

optimistic is just about right. I guess I will drive the six hour round trip so there can be a true measure of the increases. Will do two sessions..one with current mods.one with mods plus tune...then wait for a bit before I install the lower pulley.
Well I don't recall if/where I read this but allegedly the HP figures that manufacturers quote can be on the conservative side. In this lawyer up happy class action suit society, if I was promised 340BHP and my numbers showed 330BHP I'm going to instruct Sue Grabbit and Run to take up their cudgels and get me some restitution. To avoid that as a manufacturer, I would skew things to make the poorest output above the value on the tin. So you may get lucky and find your car makes 350BHP, nobody going to sue me for giving them more. Am I right ?
I believe dyno numbers can be either raw or converted/calculated to take into account same for same, so as long as the two dyno runs apply the same conversion on the data then the results should be meaningful (I think adjusting for temperature and air density /altitude is one of them).
But what do I know. Heard it from a bloke down the pub ;-)
I've had the XJR on four different dyno's in two countries and it made 300rwhp, 320rwhp, 329rwhp, 340rwhp, yet it trapped the same speed down the 1/4 mile consistently.
So a variance of 40rwhp depending on who's dyno and how happy it is when the power level is really more or less the same.
If you want properly comparable results, use the same dyno every time.
I don't know....My plan was to do two sessions because I have installed the TCP intake and the Varex exhaust on there and I would like to know what the car got out of those two upgrades. Then flash the mod onto the car and do another run to see what gains the flash was good for.

That's a good plan to really know the benefits of the mods.
Well at least you should get a good run in to acclimate the ECU ;-)
hahaha...I just re-read this and made sense of it. I load the tune before I leave...When I arrive, I put the stock tune back on....then do the base dyno....change back to the VAP tune ...dyno again...beautiful...I am so glad I thought of that...hehehe
So the dyno wont be available until mid march. I am getting that "ants in the pants" feeling !!! I don;t think I can hold off until then to load the tune
