At 16, and 130lbs with a 240 deadlift, you have A LOT of room to grow. How tall are you?
Functional strength is the name of the game as far as I am concerned, as one gains weight, the potential for pound for pound strength decreases expoentially, however, total strength increases. A 150lb guy deadlifting 3x bodyweight is at 450 (impressive for a small guy, but thats where I will leave it). A 250lb guy deadlifting 3x bodyweight is at 750 (impressive, but nothing that will be remembered in history). A 300lb guy deadlifting 3x bodyweight is at 900 (and you can count on one hand the number of people who have ever breathed who can pull 900lbs)......so you see where I am going, as you gain weight, you get stronger, period. Your strength to bodyweight ratio may not be the same as your potential to gain 'pound for pound' strength decreases exponentially, but you still get significantly stronger.
Not that it counts for much, but you're gonna get my personal opinion anyway, lol. I think the term 'pound for pound' strength is kind of a silly thing to shoot for. At 16, you're NOWHERE near done developing, and your best years of strength and growth are staring you right in the face. Some people are strong at light bodyweights (compared to others in a similar weight class) and aren't as proportionately strong heavier, although they most certainly are STRONGER heavier......on the other hand, some guys are just plain weak at light bodyweights, but as they gain they get stronger and stronger proportionately, and some of the best and strongest heavy weights would make some of the worst and weakest lightweights.
Please don't take this as me making fun of you, because I'm not. I say this because I want it to fuel you and to set a higher standard for yourself that I feel at your age and level you are MORE than capable of. Look at it this way. 240lbs is not a good deadlift in the grand scheme of things. I know a female triathlete, who at 5' 6" and 130lbs can deadlift 225 for a double without even really training with weights. For you, At some gyms, in some high school weight rooms, a 240 DL may garner respect, but I am telling you,240lbs for an adult male is not a strong deadlift by any stretch of the imagination. Don't set limits like "Well, I weigh 130, so whats the strongest I can get being small".....just get strong, think of things like 300....400.....425....450.....500....550.....set up a long-term plan with long-term goals......and EAT....your body will find a comfortable natural weight that you are strongest at, don't sweat thing like bodyweight ratio lifts right now, you're too young, have too much natural testosterone in your body, and have TOO much potential to set limits like that on yourself.
All that said, you're are on the right track, take what I said as encouragement, If you were 63 years old with 3 herniated disks and had undergone triple bypass, I'd say a 240lb DL is inspirational, but when I hear "16 years old and 130lbs" all I see is endless POTENTIAL....don't set limits on yourself, you're entirely too young and inexperienced to build a ceiling over your head.
