Yes, I typically find you can fatten up the EHA just a hair for better
peak torque/HP...the cars usually come a touch lean from the factory.

Ideally you want to be able to tune w/ a wideband O2 so you know you're
not going too far..  However, that aside you can usually pull the screw
off the back of the EHA and give the 2.5mm hex a 1 flat turn to the right.

Thank you Jonathan,
"1 flat" or 30 degrees, correct?
