Go back and ask for your money. The dyno is completely miscalibrated.

Minimum figures in the negative and performance figures plotted against time? Wtf

Avoid it like the plague my friend, engine related screw ups are not easy to fix.

Looking more why did they stop it at 6k on the 4th gear not like it matters but even your MPH is low my 4th gear pull was 120MPH !
Does it matter that they said the cars weight is almost 5000 lbs? Wth

If you can find a dyno day, a lot of tuning shops will give you three pulls on the dyno for 60 bucks. Otherwise, I think 75-100 is reasonable for a dyno pull. If you want a tune, it's the license plus tune. 550-650 all in, with ~100 dollar retunes.

60 bucks for 3 pulls?!
Price in my country is from $20-25 for three pulls and $50 for a 1 hour rental and $100 if its AWD.

Anyway ask for your money back. that dyno was definitely miscalibrated.
