Went back to PBIR to see how Cobb's new v403 map stacks up and this test and tune confirms what my butt dyno has been saying all along. There is no doubt that v403 is a smoother map than v402 and I commend Cobb for bringing out such a map, but there is something about the beta v402 that I like even more. It feels like it has more balls in 3rd and 4th gear. Well, without further ado:

2008 135i
Cobb OTS E30 maps
Helix FMIC
Raceland downpipes
Stock everything else including stock runflat tires
Unfortunately after those clean runs, I started misfiring on the way back home. It sucked because I wanted to show BuraQ how much balls this car has without meth (spun at 50mph in 3rd gear and then misfired lol).:naughty:
