Here is a plot of two of my rolliing road plots the differences between the two are the rolling road and the difference between standard and equal length headers. Now I know that there is a HUGE variation between RR's and that they should never be used as an absoloute reference but there is no mistaking the 1000 rpm difference in the torque and hence turbo spool up. This made the car feel quicker but only because it was ultimately slower at the bottom end.
So do I spend some time this weekend putting the standard ones back on (with a little porting too
) or should I just leave the equal length ones on and be happy that peak torque has gone up by 10 Lbs/ft?

Sorry, just seen how poor photbucket has resized the graph, green is the standard headers and the blue is the equal length

To tell you the truth I think I just need to cut my losses with them. They were cheap, don't fit very well, oil filter is a PITA to change......... but do sound very very very nice!
anyway no one on here will by them after seeing my RR results

No, but the fueling was checked on the road and on the rolling road, it is a bit rich durring spool up but I really don't think this can account for the difference?
