| | 546rwhp unlocked NA
Last time on a chassis dyno with my old heads cam and unlocked 4l80E I made 469rwhp on 91 octane and 28* timing.
Today with 20* timing I made a pull with 91 and laid down 511rwhp.
With E48 I turned timing up to 28* peak tq and 26* peak hp (what it liked, tried a bit more with no gains), made 546rwhp.
Drained the tank again and put E85 in. Did not gain anything on E85 compared to E48.
Dyno sheet coming.
