This weekend I filled up with 93 octane for the first time in prep for my diablo predator going in tonight. For the last two days when i get on the main road and run through first gear (upto 4k rpm) when i let of the gas to shift I get some pretty loud popping like sound coming from the exhaust. After that first time it doesn't happen again...only in the morning after sitting all night. Anyone know what this could be and if it is caused by the 93 octane gas? Will this go away when i put the predator performance tune on tonight? Mods are in my sig.

Tks for your help
