That’s right around where it should be, mine runs the same way. I also have a full tilt intake manifold (gains are negligible at this horsepower) but I installed it even if it helps a mere 2% it’s still an improvement in my eyes.

Avoid lugging the motor, otherwise it sounds like your tune is doing what it should. Uni knows what he’s doing
