I went to the track friday and bested a 12.7 at 110 with all my mods. I went earlier and ran a 12.7 at 107 N/A with just 4.30's, no cats, and a JLT. My car felt stong until 5500 rpm and in third it felt like it was struggling. It threw a MAF sensor Hi voltage code. Im running a 90mm lightning maf. I was wondering how i could data log with my X2 and then get it onto my pro racers package? I want to order a B2400 or B2800 but im not sure of the difference, any help is greatly appreciated......
