[QUOTE="01yellercobra, post: 15962091, member: 35549"] When you installed the BA2600 MAF did you have the car retuned for it? As for the drive cycle code chances are the tuner turned off the rear O2’s in the tune. If they’re turned off the cycle will never complete. The MAP sensor shouldn’t be an issue. Lots of people running over 17psi with no issues. First thing is to fix the alternator. Whether it’s a bad connection or the alternator going out. There needs to be a steady supply of voltage for everything to work correctly. To be honest I wouldn’t be surprised if that’s the issue. If the voltage is low the pumps can’t keep up. After that I would start datalogging. See if you can replicate the issue and catch on a log. If you can you’ll probably be able to figure things out quick. [/QUOTE]
