I'm going to log it for sure, but I don't see it needing a retune. That's the beauty of a well setup ROM based ECU...and a MAF setup

It adjusts accordingly and works well regardless. Sure I may be able to squeak some more out, but I think it'll be just fine. I'll be the first to report back if it isn't though...If It does need a retune I'll certainly be going to a 4 bar fuel setup and increasing the dwell times on the LS packs and cranking the boost.
