An intake would help a good bit.
18% is an average difference between dynodynamics and dynojet. you can also use this...
POWER-TORQUE-RPM
as an idea... your 291 on a DD is ~342 on a DJ, but those numbers are guaranteed until you get on a DJ and really see what it puts down.
DD's vary widely dyno-to-dyno; I've seen DD results that are less-than, approximately equal-to, and yes, occasionally greater-than DJ results for the same car.
As they (DD's) are typically lower, I've seen 'guesstimates' that proper % losses for our platform to compute output at the crank, DJ is 18% and DD is 20-22%. So even using the more-aggressive 22% factor, 291rw would be ~373 at the crank (up from 349), and likely would result in ~306 rw on a DJ.
I've never seen "18% is an average difference between dynodynamics and dynojet" - source please?
