I currently have my base LTRIMs at -3.1. I want to tune it on a dyno that has a wideband O2. How much power am I compromising by tuning my WOT on the wideband O2 with the MAFT vs LS1Edit. I have seen a fellow C5 member with TR224 Cam, pulley, intake, headres, blah blah pull 380 RWHP with wideband O2 tuning via a MAFT. That's pretty good IMO for using a MAFT. I guess I'm curious as to how much I'm losing by tuning to the proper A/F with the MAFT on the dyno? Thanks.

You can get pretty close with a MAFT. The main issues are you can't change spark and the A/F tweaks needed at peak torque (e.g. richer) may not be the same tweak needed at peak HP (e.g. leaner).

Thanks, Ragtop 99.
