Correction Factors the same as bench racing?

But can you tune in shootout mode properly? Making pulls to see horsepower and tuning is different. I use a Dyno dynamics quite often at a friends shop. I just can't deal with constantly changing ramp rates as power goes up. I do love to tune drivability/low load on it though. Gets the job done in 1/4 of the time as a dynojet

But DD shops here in the states like DG and "The Shop" tweak their numbers to the max so they stay away from shootout mode like the plague.

I tune the car and I run the logs through myself. Cant fudge nothing there. 4WS stays in my sig and always will cause hes supported me and my car since the start of Open Source tuning. I do mostly my own tuning now and if I need assistance, advise, or questions I call Tamer 
700 #s is ALOT to take out of a car. Hell Ive scrimpted and saved every OUNCE that I could and I can barely get mine under the 3k pound mark with me in it. And when I say barely, i mean pounds.
Ill lay my car down for example:
2950#s (me in it)+708 hp= 159.5 mph
A 3,000# pound car with 700 hp (mustang dyno) should trap high 150s/low 160s.
Examples: Bad Bish, My car, AWDs RS
A 3,000# pound car with 600 hp (mustang dyno) should trap high 140s/low 150s.
Examples: My car on old set-up, VW Jeff, SloRice, Spin2GST

My interpretation of TTP's essential argument is this: The motive for any shop in a non "tropical" environment using uncorrected figures is that they wouldn't benefit from using WCF because it would lower their HP/TQ figures.
This, to me, is a paranoid argument. Buschur, GST, CBRD, EPIC and whoever else has Mustang dyno's use it for the very same reason TTP does: for it's ability to load a car to their taste. Which is a great reason! They just don't use Weather Correction because they believe it creates an artifical number--which is true--and the whole point of this thread.
Also, Buschur challenged TTP to a race. This challenge seeks to prove which shop is better based on which shop owner's personal car is faster/quicker. Period. Now, why would TTP ask for both cars to be weighed? How does your car's weight matter in a competition for best built car? If your car weighs 500lbs more than Buschur's but is just as street legal and has virtually the same features/amenities then the only person to blame for the loss is yourself.

And Buschurs car races with the exhaust on, all the seats in, and not half stripped 
If the car is built with the right parts, it can weigh more and still be faster. If correction factors are used by your comments:
Your car makes 768 whp (if i remember correctly)
Daves RS would make about 675 (colder climate lowers HP)
So your 100 whp more should be plenty to cover a weight difference.
Hell, 100 hp took my car from a 9.90 car to a 9.4 car.

Come on now. If you are talking about your car you ran 143 with NO seats, NO exhaust, NO wing, NO spare/trunk accessories, and who knows what else. Where in the world could you find 700 more pounds?
The message is very clear
Educated and inteligent customers need to ask questions when they dyno
> IS a correction factor being used ?
> If So may I please have a print out with and without a correction factor?
> Understanding how each dyno works and how the correction factor can be manipulated and adjusted and how the various secret settings change the power reading
At the end of all of this if a few customers are informed and understand what the numbers mean and how they can be manipulated then I'll be happy
