Looks healthy! What boost are you running to get there? Curious to compare to the 6758, should be fairly similar at medium boost levels on pump, but how much less does it take you with e85

Takes me about 18-19 to get there on 93

15psi. I’m told my timing is very conservative for e85

OEM pistons for an 03 would be 10.0:1 for a USDM block.

EDIT: Appears OP already got it
