Help with Power Comander 3 mapping
I have a 2005 ultra Classic with Stock TC88 motor with Screaming Eagle true duels, Screaming eagle A/C and a stage 1 ECM. Im installing Andrews tw21 cams and the only mapping for Power Commander that I can find thats even close to my configuration has 95" flat top pistons. Does anyone know if there would be a big difference in mapping from a stock 88 to a 95?

No way to really know for sure but the 95" would need more fuel than the 88" and you're already stage 1 on your ecu so I would guess that the 95" map would be too rich. But-You've got to start somewhere and a bit too rich is better that too lean. You could fine tune it with adjustments after several rides to dial it in somewhat but the canned maps will never be exactly right for your engine.
I would agree that the best solution would be to get it on a dyno but $$.
