it was brought to my attention that my dyno lines looked weird, jaggedy to be exact. i have never dynoed till this particular night so i am not familiar with any occurences that might be odd. to tell the truth i never really looked at the lines just the digits. anyway, has anybody ever seen a dyno with lines as jagged as mine? my friend dynoed the same night, he said he doesn't think his lines showed up on his sheet like mine. the guy dynoing my Z had a problem hooking up the tach sensor to the coil. i think he got it on the third time or did he? if that were the problem, would it show up on paper the way it did. a friend also suggested that my tires may have been slipping on the rollers, like if i had oil from the shop floor on my tires. ever heard of that happening? could cats vibrating against the chassis of a vehicle cause such weird lines? mine vibrate for a split second when i get on it. if any of you guys or girs know what might be that cause of the jaggedy lines please post a reply. i will call the shop tomorrow to ask them about it. they might be closed because we have a storm heading our way. thanks in advance.

here is the dyno

 

talked to the shop today. i was told not to worry about it, that most likely my car was running rich at lower RPMs. what do you guys think? he also said that he sees this alot in mustangs because the torque comes on so early. now i feel like i need an air/fuel meter. if he is correct and i am running rich, you guys think that my mods could have caused such a condition (pop charger, borla TD, ur pulley set, kinetix cats)? if so, if i lean it out a bit i will make more power right? how much is an ecu reflash? also, what are the different ways in which the air/fuel ratio can be adjusted? what would be considered prime?
