I installed the DC today for my first dyno pulls. I must first say that I was very impressed with the numbers gained with this IAC. BUT, on the way home (~3 hours drive) I noticed that I now have a tip in stumble/hesitation. Now, I forgot to unplug the battery when installing the DC to reset the ECM. Could this be a reason for the stumble? I also removed the MAF screen. Any ideas on this one guys?
