Is there anyone who has had their stock S4 N/A dyno'ed? I'd like to see the sheet. I saw one guy's on here that got it from the junk yard, but is that torqe dip at 3800 from a the hesistation i hear about, or is it from the ports opening up?

 

if you are talking about the blue car, that some guy has posted a little while back then yes his dip was a bit harsh, normally it woudl only bea couple HP. that dip is the secondary injectors kicking in and not the 6 ports, since his 6 ports were operated manualyl opena dn closed at diffrent runs.
