Meh, getting there. Good thing I get free dyno time. Just need to figure out if the COPs are iffy. I need to log cylinder misfires. TR6's gapped @ .030.

A/F needs some fixing too. What makes you think your COP's may have a problem?

Did change A/F and checked everything else. Seems electrical causing misfires. Almost blew my exhaust off the car yesterday getting on the highway! :D BOOOOMMM!!!! Scared the crap outa me!
Very similar dyno chart with misfires (not to mention that's what the pros are telling me):

Found out why the misfires are happening in the middle of the run. The alternator was turning off @ WOT and turning back on towards the end since the voltage dropped so low. I set it to stay on in the tune and it;s much more smooth throughout WOT. Back to dialing in timing and afr!!! :banana2:

I have mine turned off too Bill - was causing lean fuel conditions with lack of power to the BAP. Very little power to be gained in turning it off.
