    Jacob, I chased a bad FPR last year kind of gave me the same symptoms. All looked good at idle but no increase in fuel pressure with boost!

    Check the fuel pressure during boost and see what it tells you.

    When Dave was tuning mine last fall he ran into the same thing. The coil pack was cracked and shooting spark sideways from six different burn marks. Look at it closely. The burns are hard to see.

    Jacob - with the way the Whipple outlet sits against the coil plug on your car - Al suggestion would be a good thing to check out! Although still, it look like the miss may only be on Bank 1 per the datalog.

    Well, it's physically the easy part...mentally, maybe not. Not as much sweat as working on exhaust....right?

    I will be in California for a training class next Tuesday and Wednesday, then catch a flight with 2 layovers to arrive in STL on Thursday morning around 8:30 am. I will be at the hotel on Thursday. I will be loading my car this weekend and hoping I don't forget anything. I still have an intermittant tach issue.
