Also had the heavy factory 20" wheels on it . Would swapping the wheels make a difference?

Not too shabby. The heavy wheels did hurt the numbers a bit, but numbers are just numbers. How does she drive ??

It runs good with the 20's but it's like I pick up 75 hp with the factory wheels and the drag radials . There is 120 lb. difference between the wheels and tires. I have the factory fullsize truck maf/with screen and a restricting filter. Would removing the screen make any difference?

I don't think I am the most qualified to answer your question. I am sure somone else with experience on dyno numbers relative to heavier or lighter wheels will chime in. Good luck.
