In response to the locked thread, I think it is important to question the products and services of companies on this forum - it is what prevents consumers like us spending time and money dealing with sub-par operations.
But I think the thrust of binkas thread was disappointment with the accuracy of dynos in general, and from someone coming from a profession where +- 20% is usually the margin of error, I look at any plot mindful of reality - so that 60 hp on a dyno chart always means 55-65 to me...so you can forget about seeing those minor tweaks on the chart - that is, unless you want to see them.
