That 3.95 was with 1' rollout (4.15 without - not nearly as impressive lol). If you're still getting stock-like numbers with stage 2+ or e30 maps, something must be up. Get some logs and see what boost/timing/afr/etc look like. I've only used MHD to load the Burger back end flashes to run with the JB4, so I have no experience with MHD OTS tunes. From what I've gathered reading the boards, their tunes for EWG turbos are more refined than their PWG tunes.
I've never messed with the xHP customization options, but maybe tinkering with the shift map editor could help.
