I have watched all of the merlin video series and also read a ton on this forum about Evo scan and ecuflash. But I still don't understand what pulls I need to record and then how to interpret them in order to "tune" for a cat back exhaust and a short ram intake. Any advice, guides or directions is much appreciated

 

Hook up your Tactrix cable and wideband and then do a WOT pull from 2500-7500. Then sit down and just go through it on excel and livemap on EvoScan to get a better picture. Half the stuff I read doesn't make sense to me until I actually do it and then it all makes sense.

 

I don't have a wideband. I just picked up the tactrix like a month ago
