LM4 dyno
Here's my dyno last night from my LM4. Base tune from Brendan at lt1swap.com. I'd say the tune's damn near close enough. We datalogged the run too, no misfires, no knock, etc., on 89 octane. Only mods are an '01 LS6 cam, and blockhugger headers with dual 2.5" pipe Y'd into the stock Volvo muffler.
