Stock / Stock + Software then Stock vs software vs software + full exhaust (including cats)

The "stock" curves in the 2 charts don't match. Why not?

because they change the scale to suit (on the bottom of the dyno) - its not my dyno - I just take the car there & ask for the graphs to be overlayed!

I want to do one with the underdrive pulley when it arrives!

P.S - just looking at it - the top dyno is scaled X axis is 250kw on the first & 220kw's on the second. The Y axis is 7000 rpm & then 7450 rpm or similar.

No, that's not the problem. I can read the different scales. The run numbers for the 2 "stock" runs are different. Also, in the 2nd chart the "stock" line (run 001) and the "software" line (run 006) touch at about 5200 RPM, but in the 1st chart they do not.

Just rang the dyno operator- the run numbers are correct - the stock pulls (numbered 3 & 1 ) are the stock pulls - the operator generally always runs three pulls (numbered one two & three).

And obviously run 6 is run 6 on both dyno's and run 9 is run 9 - whats the problem with the dyno's - you have me confused?

I could always get them to print me out nine seperate dyno sheets, but I don't see the point or I could get them to put all 9 runs on one but then you would really struggle to read it!.

Actually better yet, contact the dyno operator, his name is Steve (nice fellow) - he will run through it all for you : contact details here:
