Car: 2008 135i
Mods: BMW DCI, Secondary cat delete
Tune: COBB AP Stage 1 Agressive
So I finally got to try ou the COBB AP tune last night here in South Florida and wanted some opinons...
Bone stock, the car went 13.9 @103 MPH. I was a little disapointed but figured the software update had something to do with it. Installed the AP and felt a nice increase in power. I then piped out the secondary cats and came to find out the drivers side secondary cat converter was partially clogged...
Went to the track last night and my first pass was:
60' - 2.013
330 - 5.517
1/8 - 8.403
MPH - 85.43
1000' - 10.884
ET - 12.973
MPH - 108.35
So I dropped a second off the stock time and gained a few MPH. Should I be happy about this or am I suppose to be expecting more? The car moves, and feels solid in the power band. shifts nice, but I expected my MPH to be around 110-112.
Temp was 82 degrees, sea level, and no wind nor any humidity. the 4 runs after this were all 13.0 passes. Thanks for any input
