SLP says no addditional hp gain. Through a set in at the end of last season, but winter ended before I could test them out. Have other mods done, thought it couldn't hurt. What is more depressing is the whole air intake passage into the motor. IMO the bottom of the air box looks restrictive, then the throttle bodies are offset to the MAG side, then they angle the intake manifold back to the PTO side. I believe this is done for chasis clearance.
Finally, thanks for some replies. I was worrying it might lean it out too much.
